I have 2 55 gallon tanks. Was wanting to put some fish that won't out grow it. Was thinking a group of silver dollars in one. And the other one a school of bala shark's.
If you want to do 2 setup next to eachother or ontop of eachother something that would be cool is to put fish in the one and put the same type of fish in the other one but albino versions of the fish in the first tank
