Only if you run a canister filter and keep them in groups.That is a beautiful fish! Can I fit one in a 5g? ;-) Speaking of lazy snails... my trochus snail is really hard working but my margarita snail doesn't seem to do anything. He certainly doesn't eat the algae which is what I got him for. LOL
I am thinking that I need to get more trochus to motivate the others. They don't know how good they have it.
