Hopefully, there's no question too dumb for this forum! We just started with a tiny one gallon tank for my daughter, Dana, who thinks she wants tropical fish in her room but hasn't had the experience I had years ago with normal-sized tanks and the effort they seem to require. We just set it up with a pair of Orange Von Rio Tetras and one Gold Snail. We are told that is almost more than the tank can handle. I note that some talk about feeding bottom-feeding fish as though the algae isn't enough. Does this mean we need to feed the snail? We are advised to clean the tank completely, periodically even with the snail so I guess he gets more than he needs to eat. What's the deal?
