As for what kind of tank you will need: Basically a square fish tank, do not get a bowl. You will likely need a heater and an air pump, and a thermometer, It is easiest to by a complete kit at a pet shop. As for size of tank: The bigger is always the better....however a minimum size will be determined by the type of fish and their average size they will grow into, So once we know what type of fish you have and how many, we can tell you how big your tank needs to be and what type of "furniture" (rocks, plants, gravel) you will need.

In general these fish can all be housed together safely. The one thing to keep in mind is the amount of space needed per fish to maintain a safe and healthy environment. Each 1in of fish needs 1 gallon of water. So in a 20 gallon tan you can have 20 inches of fish. The Pleco is the only one I have concerns with as some varieties can grow quite large. Check with your local pet shop as to what needs best suit this type of fish or what type of fish suit your tank best.

It is possible the tank has not cycled properly which results in high ammonia and nitrite levels which can kill fish. Allow the tank to run, without fish, for at least 4-6 weeks. During this time, use a home test kit or submit a water sample for testing every few days. The local Petco may do this for free or for a small fee. What you are looking for is to have ammonia and nitrites at 0 ppm and nitrates at 20ppm or less. pH can hover around 7 for most community fish. Avoid large, rapid swings in pH though. What is happening in the tank during this time is that beneficial bacteria are populating the gravel/substrate and the filter. These bacterial populations are responsible for the Nitrogen Cycle. This cycle breaks down wastes from fish, uneaten food and plant matter into by-products that are filtered out or dissipate. You can "cycle" a tank with fish, however this increases the risk of loss. Once your tank has cycled, you can add fish. You will still need to monitor water chemistry a

To safely mix fish species together, there are a few considerations to keep in mind. First, you want to choose fish that have similar temperature requirements as your betta. Otherwise the fish can be stressed. Second, you want to get species that have similar oxygen requirements - bettas don’t need a lot of bubblers in their tanks, but not all species are like that, so unless you want to do some adjustments to you betta tank, it is a good idea to get other species that don’t need a lot of oxygen. Third, it depends on how many gallons your tank is. Overcrowding is a common problem for many fish owners, and it can make it very difficult to keep up on the water quality. The general rule of thumb you can use is one square inch of fish per gallon. When using this rule, go based on the adult size of fish, because often people get fish that are young and small and don’t anticipate that they will get bigger! I would advise getting your thoughts together about the parameters above, and then vi
