I've been wanting one of these guys for a while now, finally got the money to get one. He's growing out in a 45 gallon with male guppies and Mystery Snails. Once he's big enough to bot get his butt handed to him in a fight, he will move in with the young Convicts in the 75 gallon. I'm hoping he can be used when I need to cull off any deformed fry, let him eat them so I won't feel as bad. Also use him to dwindle down the Convict population when they breed again. I think he's my new favorite.
