Types of Pond Fish

Colorful koi

When it comes to outdoor ponds, koi are the most well-known species of ornamental fish used for stock. Koi come in a variety of shapes and colors including black, gold, red and orange. These fish look similar to goldfish but grow much larger and exhibit a wider variety of shapes in their fins and bodies. Because they grow to be quite large, koi require a pond capacity of at least 1000 gallons in order to thrive. These fish also require a variegated diet including fresh vegetables, fruit and specially formulated koi foods.

Goldfish come in a variety of shapes and colors which makes them a popular choice as a pond fish. Some of the most popular varieties of goldfish include Comets, Shubunkins and Orandas. Comets come in red, orange and white varieties – the calico varieties are called Shubunkin Comets. Orandas are a type of fancy goldfish known for the prominent hood that develops on top of its head.  In general, goldfish are a hearty species which does well in ponds with adequate filtration and aeration. Most goldfish prefer peaceful or slow-moving water and require a pond capacity of 250 gallons or more to thrive.

Precautions to Take with Pond Fish

Just as you should exercise caution when stocking your home aquarium, be careful when selecting the fish for your pond. Some species can grow very large or may become aggressive around other species. By doing some research before you purchase your pond fish you can prevent a disaster from happening later. Comets, for example, can be aggressive and should not be mixed with most other types of pond fish aside from koi. Goldfish and Orandas are generally peaceful species that can get along with a variety of species.

Tips for Keeping your Pond Healthy

A healthy pond requires routine maintenance in order to keep water quality high. Because goldfish and other pond fish are notoriously high producers of waste, adequate filtration is key to maintaining water quality. To give your pond a boost, consider installing one or more EcoBio-Block Waves. These blocks are infused with beneficial bacteria that multiply naturally to establish a colony in your pond. Once established, this colony of beneficial bacteria will help to break down organic waste products, remove odors and clarify cloudy pond water. While you should still maintain proper filtration and execute regular maintenance procedures, an EcoBio-Block Wave can help to keep your pond clean and healthy for your fish.

Types of Fish That Eat Aquarium Plants

While many species of aquarium fish are likely to nibble on the plants in your aquarium, some are capable of decimating your entire planted aquarium in a matter of hours. Silver dollar fish, for example, are particularly notorious plant eaters. Other species like mollies and swordtails may nibble at your plants but will rarely do any major damage. Though they may not actually eat your aquarium plants, some larger species like gouramis and cichlids may uproot and break apart the plants in your tank and algae eaters may chew holes in them.

Species of Fish Safe for Planted Tanks

If you have taken the time to cultivate a planted tank you should also make the effort to ensure that the fish you add to your tank will not destroy all of your hard work. Most small, community species of fish pose no threat to aquarium plants. Barbs, tetras, danios and guppies are all unlikely to do anything more than pick flakes of food from the leaves of aquarium plants. Even some of the slightly larger species like discus, killifish and dwarf gouramis are safe for planted tanks. Other species that are recommended for planted tanks include corydoras catfish, platties, gobies, minnows and betta fish.

Tips for Maintaining a Planted Tank

Healthy Planted Tank

There are many benefits to cultivating live aquarium plants in your tank. Not only do live plants enhance the aesthetic appeal of your tank but they can also increase the oxygen level and help filter out harmful toxins. In order to keep your aquarium plants healthy you need to provide a healthy aquarium environment. To create this type of environment you will need adequate light, nutrition and filtration.

In addition to these three things there is something else you can do to keep your tank a clean, healthy environment for your plants and fish. Introduce an EcoBio-Planter to your mid-size aquarium as a simple way to remove odors and clarify your tank water (for larger tanks, simply add another planter or a stone). EcoBio-Planters are made from natural zeolite and crushed stone which has been infused with beneficial bacteria. Once introduced to your tank, these bacteria will multiply and establish a colony that will then work to break down wastes, remove odors and speed up the nitrogen cycle. EcoBio-Planter is also terrific for your plants. Simply place a small root ball in the opening and the plant will grow and thrive, greatly adding to the beauty of your planted aquarium.

Choosing an Algae Eater

When it comes to selecting an algae eater for your tank there are several options to choose from. Before you visit the pet store, however, there are a few things you should keep in mind. An algae eater is different from a bottom feeder – these two types of fish are both useful in the home aquarium but they serve different purposes. Bottom feeders primarily feed on uneaten fish food and sinking pellets. While some algae eaters perform this function as well, many are known for their suction cup-like mouths that enable them to clean algae off the glass and decorations in your tank.

Types of Algae Eaters

Pleco Fish

One of the most well-known types of algae eater is the plecostomus, often called the pleco. These fish are a species of semi-aggressive catfish and, provided enough space and food, they can grow to two feet in length. This type of algae eater is recommended for large tanks where they can be kept individually or with a small number of community fish. Another type of catfish, the Otocinclus affinis (Oto cat), is another popular algae eater. These fish generally stay under two inches in size which makes them the perfect algae eater for small aquariums. Oto cats are typically not aggressive so they do well in community tanks.

Another popular species of algae eater is the Siamese algae eater, or Crossocheilus oblongus. These fish are typically friendly, though as they age they may become aggressive toward others of their own species. Siamese algae eaters are unique among algae eaters because they feed on the red algae that many other algae eaters tend to avoid. Gyrinocheilus, or Chinese algae eaters, have large suction-cup mouths and can grow up to ten inches long. Though generally friendly in their youth, older fish of this species can become territorial and aggressive.

Tips for Keeping Algae at Bay

While introducing an algae eater into your tank is one of the easiest ways to control algae growth there are several other things you can do. Keep your tank out of direct sunlight and perform regular water changes to keep the water quality in the tank high. You can also install an EcoBio-Stone in your tank which will maintain good water quality and help to keep your tank clean and algae-free. EcoBio-Stones are made from porous volcanic stones and cement and are infused with special beneficial bacteria that multiply in your tank, working to break down wastes and speed up the nitrogen cycle. Combined with an algae eater and routine maintenance, an EcoBio-Stone is an easy way to keep your tank free of unwanted algae.

Quarantine tank with EcoBio-Stone S

When one of your fish falls ill it may only be a matter of time before the disease spreads to your other tank inhabitants. For this reason it is extremely important for you to keep an eye out for the early symptoms of disease. If you catch the disease early enough you will be able to quarantine the sick fish in a hospital tank to ensure a speedy recovery and to prevent your other fish from falling ill. A hospital tank, or quarantine tank, is a fairly basic set-up and it is generally easy to maintain.

Setting Up the Tank

Because you will usually keep just one fish in the hospital tank at a time it does not need to be large – 10 gallons is a sufficient size. The bottom of the tank should be kept bare of gravel or other substrate to facilitate easy cleaning and to prevent the build-up of disease-harboring bacteria. Do not over-decorate the tank – simply provide a few plants or an overturned terra cotta pot to give your fish places to hide. Hospital tanks have very few requirements other than clean water and adequate filtration but you need to choose wisely when selecting a filter for your tank. Power filters that have a low setting are generally recommended for hospital tanks because they provide both chemical and mechanical filtration without creating a current powerful enough to disturb your sick fish.

Using a Hospital Tank

When you notice the symptoms of disease beginning to manifest in your tank, set up your hospital tank as quickly as possible. Use as much water from the original tank as you can when filling the hospital tank in order to decrease the amount of stress your fish experience in switching tanks. Use an in-tank thermometer to monitor and control the water temperature in the tank and administer whatever medications your fish require on a regular basis.

Other Tips for Hospital Tanks

If you have a large tank with many fish, it may be wise to set up a permanent hospital tank. By doing this you can rest assured that if one of your fish happens to fall ill you will not be putting the rest of your fish at risk by delaying the removal of the sick fish from the tank. A hospital tank can also be used as a quarantine tank when you bring new fish home from the pet store. To prevent the spread of disease you should always quarantine new fish for at least seven days. This will ensure that the new fish do not pass an existing illness on to your other fish.

A quick and easy way to ensure that the water in your hospital tank stays clean and clear is to use an EcoBio-Stone. EcoBio-Stones are made from porous volcanic rock and cement block and they are infused with nutrients and beneficial bacteria designed to keep your tank healthy. Once introduced into your tank, these beneficial bacteria will multiply and work to speed up the nitrogen cycle, keeping your tank water clean and clear. Not only do EcoBi0-Block products help keep your tank healthy, they also reduce the amount of routine maintenance required.

No matter how careful you are in caring for your aquarium fish, the chances are good that you will eventually experience the outbreak of some kind of disease. By acting quickly in setting up and utilizing a hospital tank, however, you can effectively curtail the spread of this disease. Learning how to set up a hospital tank, and then putting that knowledge to use, is a simple way to ensure that your sick fish recover quickly and your other fish do not fall ill.

Aquarium Substrate

When it comes to setting up your aquarium for the first time one of the most important decisions you can make is what type of substrate to use. Many first-time aquarium hobbyists do not even realize that they have a choice beyond natural or colored gravel. While gravel serves its purpose well as an aquarium substrate, there are other options and some of these options have additional benefits for your tank. If you plan to keep live aquarium plants in your tank it is especially important for you to choose a substrate wisely.

Different Types of Substrates

Gravel : As one of the most readily available types of substrate, gravel is also one of the most popular. Not only is gravel easy to find and inexpensive to purchase but it comes in a variety of shapes and sizes which makes it a great option for hobbyists who want to customize their tank. Another benefit of gravel substrate is that it can be relatively easy to clean – you can simply remove it from the tank and rinse it in warm tap water until the water runs clear. Gravel can also serve as a base for the growth of beneficial bacteria but it does not provide any nutrients to support the growth of live aquarium plants.

Sand: Sea sand is not recommended for freshwater aquariums but it is popular for use in marine aquariums. This type of sand often contains impurities which can cloud the water and it may also contain pieces of shell or coral that can raise the pH in the tank. Play sand, however, makes an excellent substrate for freshwater aquariums because it has been sterilized and requires less-frequent cleaning than aquarium gravel. Aragonite is another popular type of sand substrate that is useful in buffering pH levels in saltwater aquariums.

Vermiculate: This substance is a substrate composed of the minerals aluminum, iron and magnesium. This substrate has a high cation exchange rate which helps aquarium plants to utilize nutrients. Vermiculate is an excellent substrate for planted tanks because it releases nutrients over a long period of time which negates the use of fertilizers. The best way to use this substrate is as a lower layer on the bottom of the tank covered or mixed with a layer of gravel.

Laterite: Laterite is a type of porous clay, often reddish in color, which can be used as a substrate in freshwater aquariums. This type of substrate attracts and holds nutrients, storing them until they can be utilized by aquarium plants. Like vermiculate, this substrate is best used as a lower layer in the home aquarium, covered by a layer of sand or gravel.

Tips for Using Aquarium Substrate

Do not think you need to limit yourself to one particular type of substrate. If you have a planted tank it is wise to combine several types of substrate, like vermiculate and laterite, with gravel or another substrate in order to provide the necessary nutrients. In conjunction with the right substrate, introducing an EcoBio-Stone is a great way to keep your tank clean and healthy. EcoBio-Block products are made from porous volcanic cement that has been infused with beneficial bacteria. Once introduced into your tank, these bacteria multiply and help to keep your tank water clear and odor-free which results in less maintenance on your part and a healthier environment for your fish.

Typical Aqurium Tank

There are several common misconceptions surrounding aquarium size. One of the most common mistakes a novice aquarium hobbyist can make is to think that a larger tank is more work to maintain than a smaller tank. In many cases, the opposite is true. When choosing the right size aquarium there are a variety of factors to consider including the level of maintenance you are willing to perform, the space you have available in your home and the types of fish you want to raise.

Tank Maintenance

If you set up your tank with the right equipment there should be relatively little maintenance involved, regardless of your tank size. Your aquarium filter will do most of the work in keeping your tank water clear by filtering out waste and toxic substances. Larger water volumes equate to a greater level of forgiveness for mistakes on the part of the aquarium hobbyist because higher water volumes dilute toxins better than small volumes. The water in smaller tanks must be changed more frequently than that in large tanks to prevent it from becoming too hard.

How to Choose the Right Size Aquarium Tank

The size and location of the space you have available in your home should be one of the major factors in considering the right size for your aquarium. You need to be able to place your tank in a low-traffic area out of direct sunlight in order to prevent accidents and excess algae growth. Before you shop for your tank, measure the space where you intend to install it and be sure you have a sturdy cabinet or stand large enough to accommodate the tank size you want. You should also keep in mind, when selecting a location for your tank, that you need to be able to access it easily in order to perform routine maintenance tasks.

Type of Fish

It may seem counterintuitive to select your aquarium fish before purchasing a tank, but doing so will help you to determine the right tank size. If you plan to fill your tank with small community fish like tetras and guppies you probably will not need anything larger than a 20- or 30- gallon tank. Larger fish, however, such as cichlids and many saltwater fish require upwards of 50 gallons of tank volume. When determining the proper size for your tank, consider the full-grown size of your fish – not the size at which you plan to purchase them. If you are just starting out, stick to the rule of purchasing one inch of fish per one gallon of tank capacity. This rule will help to prevent overcrowding in your tank.

Other Tips for Maintaining Your Tank

Choosing the right size tank for your fish is one of the simplest ways to ensure that they are able to enjoy a healthy environment. The larger the tank you select, the less you will have to worry about toxicity and overcrowding but not every hobbyist has room for a large tank. No matter what size tank you choose there are a few simple things you can do to keep it clean and healthy. Introducing an EcoBio-Stone, for example, is an easy way to boost the nitrogen cycle in your tank, ensuring that the water stays clean and clear. EcoBio-Stones are made from natural volcanic cement and infused with special beneficial bacteria. Once introduced into your tank, these bacteria will multiply and establish a colony of beneficial bacteria that will work to revitalize your tank water, remove odors and reduce the amount of necessary maintenance you have to perform.

Types of Pond Plants

When it comes to aquatic pond plants there are a variety of options which can generally be divided into four different groups. Oxygenators are the category of pond plants which grow entirely beneath the surface of the water where they help to increase the oxygen content and provide cover for your fish when they need it. Floating plants are those that do not need to be rooted in a pot or planter. These plants float on the surface, providing shade which helps to reduce algae growth in your pond.
Deep water pond plants like water lilies and lotus are largely ornamental. Some of these plants produce beautiful blooms which serve to add color to your water garden. The final category of pond plants includes bog plants such as cattails, grasses and reeds. These plants grow best in shallow areas and are most often used to blend the pond into the rest of the landscaping in your yard.

The Benefits of a Water Garden

The benefits of transforming your koi pond into a water garden extend far beyond the aesthetic. By adding live plants to your pond you will not only be making the pond a healthier environment for your fish but you also will be decreasing the necessary amount of maintenance as well. Aquatic plants use the waste produced by your fish as fertilizer and, in exchange, produce the oxygen your fish need in order to breathe. This is an extremely important benefit because koi require highly-oxygenated water in order to thrive. Live plants will also compete for nutrients with pond algae, thus reducing the amount of unsightly algae growing in your pond.

How to Add Plants to Your Pond

Before purchasing your pond plants, perform some basic research to decide what type of plants you want. As you research, determine what the potting requirements are for each type you have chosen. Fabric pots and plastic pots with no holes are the most common types of pots used in water gardens because they keep the potting soil contained and they can be moved easily. For those of your plants which need to be rooted, fill your pots with clay soil and anchor them with sand or gravel. Place the pots in the desired location within your pond, positioning your plants in the arrangement you find most attractive. Floating plants do not require pots – they can be left to drift along the surface of your water garden.

If you want to get the most out of your water garden, try adding a few EcoBio-Blocks to your pond. The EcoBio-Block nsM is a four-pack of water-clarifying stones made from natural zeolite and infused with beneficial bacteria. The special nitrifying bacteria infused in the EcoBio-Blocks will multiply rapidly once you have added the stones to your pond. These bacteria will clarify the water, remove odor and help to decrease the frequency of necessary pond maintenance. If the water in your koi pond is kept clean and clear, it will be a better environment for both your fish and your aquatic plants.

The Pros and Cons of Algae in Ponds

Algae are single-celled organisms that thrive in warm, nutrient-rich water. In an outdoor pond, algae are an essential part of the food chain. Algae subsist on the waste produced by your fish and, in turn, become a food source for your fish. In limited quantities, algae can enhance the appearance of your pond by giving it a more natural look but if it grows out of control algae can cover the surfaces in your pond with a green or brown slime. In addition to this slimy muck, algae can also turn your pond water an unsightly shade of green. This may reduce the clarity of your pond water and make it more difficult for you to view your fish. In addition to the aesthetic problems induced by its growth, algae can also deplete the oxygen supply in your pond water which will make it a stressful environment for your fish.

Factors that Contribute to Algae Growth

Like any aquatic plant, algae require nutrients to grow and if your pond provides an abundance of these nutrients you may experience a problem with algae. Organic matter and uneaten fish food settle at the bottom of your pond which will, over time, result in a build-up of ammonia and nitrate on which algae can feed. Direct sunlight is another contributing factor in the growth of algae so if your pond is not shaded by trees you may have trouble with algae. Though it can be harmful to your pond if too much algae is allowed to grow, most ponds experience a “bloom” of algae in the spring. In most cases, your pond will find its balance after a few weeks and return to its normal clarity.

Tips for Controlling Algae

Installing an adequate filtration system in your pond is an easy way to limit the growth of algae. Many pond filters utilize chemical filtration which helps to remove the wastes and toxins that would otherwise provide a food source for algae. Adding aquatic plants to your pond is another easy solution because plants will compete with algae for the same nutrients, thus limiting the potential for algae to grow and spread.  Introducing some floating plants like water lilies may also help to control algae growth by cooling the water and providing shade.

In addition to these measures, adding an EcoBio-Block Wave or nsM to your outdoor pond can be effective in clarifying the water and reducing algae growth. EcoBio-Blocks are made from natural zeolite and special cement that has been infused with special beneficial bacteria. Once the block has been installed in your pond it will release bacteria regularly which will work to break down organic waste into ammonia, then nitrites and then into nitrates. EcoBio-Block keeps water healthy which discourages the growth of algae. It also appears to encourage the growth of anaerobic bacteria, which changes nitrates (on which bacteria feed) to nitrogen gas. This product is a simple way to control algae and a great way to keep your pond water clean and clear with no extra effort required on your part.

Types of Pond Filter

Before you can begin to peruse your options in pond filters you need to decide between the two major types: external and submersed filters. External pond filters can be very large and are not installed directly in the pond. Because this type of filter is not housed within the pond itself it is much easier to clean and to change or add filter media when needed. Though external pond filters have the capacity to support larger biological loads than submersed filters, they can be unsightly and difficult to disguise.

Submersed pond filters are those which can be installed inside the pond itself. This feature allows you to easily conceal the filter from view using an arrangement of aquatic plants or decorative stones. A submersed pond filter can be filled with different types of filter media, as can an external filter, but this type is more difficult to clean because it must be removed from the pond first. Although submersed pond filters are limited in their ability to support large biological loads, they are extremely versatile and can be used for water features as well as basic pond filtration.

Tips for Selecting a Filter

After you have made your choice between an external and a submersed pond filter you need to select the right model for your particular pond. One of the most important factors in determining which filter is right for you is the size of your pond. Different filters are designed to support different biological loads. The model you choose should be able to filter one half of the total pond volume in an hour. If your pond is located in an area that receives a great deal of sunlight you may need a larger filter to counteract an increased rate of algae growth.

In addition to the size of your pond, the type of filtration you desire should also be a factor when making your decision. Mechanical filtration is the most basic function of a filter which involves removing solid waste from the water as it is drawn up through the filter media. Chemical filtration serves to remove toxins from the water and biological filtration involves maintaining a colony of beneficial bacteria which help to break down wastes and clarify the water.

Regardless of what type of filter you choose there are a few simple things you can do to keep your pond water clean and clear. Avoid overfeeding your fish and take steps to prevent your pond from becoming too crowded. You may also consider adding an EcoBio-Block Wave or EcoBio-Block nsM to your pond in order to facilitate the growth of a colony of nitrifying bacteria. EcoBio-Blocks are made from natural zeolite and infused with beneficial bacteria which will quickly multiply after being introduced into your pond. The presence of these bacteria will speed up the nitrogen cycle in your pond which will result in cleaner, clearer water and a healthier environment in which your fish can thrive.

Setting up a new tank

After purchasing an aquarium and bringing it home, many novice aquarium hobbyists mistakenly believe that the most difficult task is behind them. It can be very hard, after all, to choose just one tank from among a wide variety of choices in aquarium sizes and shapes. Once you get your new aquarium home, however, the real work begins. If you take time to make the necessary preparations and research the proper procedure, setting up your first freshwater aquarium will be less of a hassle and your job will be much easier down the line when it comes to routine care and maintenance.

Selecting a Location

Place your aquarium on top of a sturdy cabinet or aquarium stand and position it somewhere you will be able to enjoy it. When selecting a location for your tank, keep in mind that if you place it in direct sunlight you will have problems with algae growth. It is also important to consider accessibility when selecting a location for your tank so that routine cleaning and maintenance does not become difficult.

Basic Set-Up Tips

1. Rinse the aquarium along with any gravel, plants and decorations in warm tap water. When rinsing gravel or substrate, stir the gravel well and flush it with water until the overflow runs clear.

2. Attach your aquarium background to the back of the tank using clear tape.

3. Pour the clean gravel into the tank then fill it about 2/3 full with warm tap water. Place a flat rock in the center of the tank and pour the water in over the rock to avoid scattering the gravel.

4. Check the water temperature in the tank as you fill it using an in-tank thermometer, adding warmer or cooler water as needed to keep the temperature between 70° and 76° Fahrenheit.

5. Set up your power filter according to the manufacturer’s instruction, but do not plug it in.

6. Mount your submersible aquarium heater on the wall of the tank, but do not plug it in. Leave adequate space around the heater to ensure even distribution of heated water and do not rest any decorations up against the heater itself.

7. Install your decorations and plants in the aquarium. Position the tallest plants near the back of the aquarium and place smaller plants up front.

8. Fill the tank the rest of the way with warm tap water and add your choice of dechlorinating solution, following the instructions on the bottle to determine how much to use.

9. Plug in your heater and filter and adjust them to the appropriate settings. Read the instructions included with your filter to determine whether you need to fill the filter with water before plugging it in.

10. Wait at least 24 hours before adding any fish to your aquarium. This will give the tank temperature time to stabilize and the nitrogen cycling process time to begin.

Other Tips for a Healthy Aquarium

In order to keep your aquarium running properly you need to establish a base of beneficial bacteria – a process often referred to as cycling the tank. Adding a few fish to the tank at a time is one of the most common ways to begin building a colony of beneficial bacteria but installing an EcoBio-Stone to your tank can help you to jumpstart the process. EcoBio-Block products are made of porous volcanic cement block infused with beneficial bacteria that will multiply upon being introduced into your tank. These bacteria help to speed up the nitrogen cycle, keeping the water in your tank clean and clear for your fish to enjoy and reduce the frequency of necessary water changes.
