It has not bothered anything in the 24 nano he is in. There are Zoos, xenia, Monti caps, RBTAs and a Clarke clown in the 24. I plan on moving the 24 soon so I have to figure out what I want to do with him. I will let you know if I decide to get rid of him. I do want to get rid of the Clarke clown, as I plan to move my black clowns to the 24 after I move the tank.
