I have on RES named fluffy in a 20 gallon tank by himself. I'm currently saving up for a 75 gallon tank for him. I was wondering about the filter situation. I currently have two whisper in-tank canister filters. What do i do about filtration when he moves to the bigger tank? I know there are other filters, such as under-gravel (i dont use gravel, it gets too dirty and too much to clean). The only one i could think of is the ones that go over the side. But then how do i put a screen on top?
