Tanks

 Community tanks- 

Community tanks have fish that aren't agressive and get along with one another. They are usually small fish, but don't get me wrong you can have big fish. They usually eat flakes, pellets, or bloodworms. All tanks should have a natural look because it gives it a better feel.

Aggressive tanks-

Aggressive tanks are usually filled with fish like chiclids, oscars, jack dempseys, red devils, or flowerhorns. Usually u need a big tank with many hiding places because there will be chases and many fights. They usually eat pellets, bloodworms, or other fish.
