I have a 30-40 gallon tank (not sure gotta remeasuer the sides and cacluate) it was a gift from a friend and it was his parents adn they forgot the size. but if its a 30 gallon, what else could I put in it if all I have is guppies. I was thinking some rams. eventually I want to move the guppies to another tank, or just leave them in there with a few other fish. I want to grow out a couple of clown loaches in it for a 75 gallon tank im setting up.
