I certainly enjoy the fish. I do really like them and everytime I see them I am tempted to give them another try. They would be perfect in my nano! Just have to get a little lid made up. Feeding them the live stuff is just a challenge. Have you tried vinegar eels or microworms? Those are two very easy live cultures (stinky but easy). I can't remember if they took them. The problem is other fish in the tank that steal them away, if memory serves me right. Anyways, I am interested in trying them again so would like to hear how things go for you.
