Oscar tank size?
i have a 20 gallon tank with a 4in brown ghost knife which just hides in a pvc pipe all day. i want to put a 2.5in oscar in the tank. how long can the oscar live in the tank before it is too large and will require a larger tank?
also i have a 55 gallon tank with 3 clown loaches, 2 silver dollars, 2 platys, 2 pictus catfishes, 1 striped rafael catfish, 1 molly, and 1 dwarf gurami all under 4in. would i be able to put the oscar in that tank when it becomes too large for the 20 gallon?
