I have a 20 gallon tank that is no longer in use because its inhabitants have been moved to my 75 gallon. It has everything it needs (heater filter undergravel hood light) I just dont know what to do with it. I was going to move my clown knife into it becuase he appeared to be sick, but is now over it.
I always wanted to get 2 piranhas, but I think that will be to small for them.
please help me decide.
