I had snails in a old tank once, they kept having babies and went crazy, had a million snails. I collected most of them and donated to local fish store.
All the crazy maintenance stuff people warn you about can be solved by dumping some more critters into the fish tank to take care of it. Algae? Snails. Too many snails? Helena. General cleanup? Shrimp. Too many shrimp? No such thing.
I have a couple oscars, and have been told african catfish can live with them, have bought three dif kind, and my oscars have killed them all. Only the Pleckos have survived.
