I may pick one up to clean up my molly breeder tank, is a 30 ga good for em? And i had some questions on aggression, although mollies are not timid in any way. at least IME. Will it bully the mollies? too much stress from another fish will stop them from fertilizing their eggs inside. The geo is only about the size of a molly now and the LFS shopkeep said that they get 6 in and would be fine in a 30, and if it got too big i can trade the big one in for a small one. I also am attempting the whole ivy plant to suck out nitrates soon as i figure out a way to fit it in the tank w/o fish being able to hop out, just want to throw in live ways of cleaning other then the lil oto algae eating catfish in there now
