Community Aquarium Fish. A community aquarium is a tank thats been designed to house a variety of different kinds of fish rather than a single species. You will find that in most community tanks not all the dwellers occur in the same natural habitat but what the aquarist does is try to find those.
These fish are great to keep for beginners as they are extremely easy to breed. Most fish need space and the more they have the better they tend to get along. If you plan to keep Corys know that they need a 10-gallon tank at least.
Of course its best if you keep multiple ones in your aquarium.
