If I move the fish from the 38 in my signature to my 75, but keep close watch on things, will it still be too much? I may sell off a few of the fish in the future. I ask because I would like to put a 55 in place of the 38, in order to get a "wet pet" cichlid. I know a couple of people who have tanks heavily stocked like that, and they just over-filter, watch what they feed, and keep up on water changes. Thoughts? Experiences? Much appreciated.
