How to Set Up a Community Fish Tank

A community fish tank is one that is compromised of a variety of fish that are capable of getting along with one another without aggression. This means that you can have many different types, as well as even some creatures that can live in a community tank, such as small frogs. The most common type of community tank is a freshwater one, and there are many different types of fish that can live in one--including danios, guppies, Siamese fighting fish (one per tank) and others.

Instructions

    • 1

      Decide what size tank you want, then go to the pet store to buy supplies, including a tank in that size. You will also want a filter and heater that are capable of handling that amount of water, as well as cartridges for the filter.

      Buy gravel and any decorations you want as well. Most stores will offer a "package" deal that has all that you need in the right sizes.

      Open your bag of gravel at home and run water through it. You can do this by putting the gravel in a bucket, filling it up, and then pouring out just the water by using a lid as a filter. Gravel will often have residue that can cloud the tank if you don't remove it first.

      Place your tank in a spot where it will get some indirect sunlight, but where the temperature will remain stable. Put in your gravel, fill the tank with water, and add your water conditioner.

      Set up your filter and heater, and plug them in. Set the heater to keep the water in the mid 70s F. Let your filter run for at least a week. This will ensure the water is healthy enough to be ready for fish.

      Purchase two or three fish at the pet store, making sure that they are community safe. The description of the fish on the side of the tank should say whether it is safe for a community tank. Place the bags of fish in your tank, letting them float on the top for at least half an hour before you let them swim into the tank. This should allow enough time for the fish to acclimate to the new temperature.
