I have been keeping a 110 g and a 55 g refugium. Looking to grow into an 250 g deep tank. I have successes like my breeding clowns who keep laying eggs like a machine, for three years now. and LTA who they are greatly attached too. Had two Hippo tangs till they got about 7", traded off too big for tank. The one tried to be a carpet fish, found 10 min later and he survived, he was sure skittish after that and remained so, as far as i know both doing well. I feed my LTA a silverside once a week. I hear do not have too? That is the question should one feed them?
