Yay a question I can sorta answer, lol. For now, my moorish idol leaves my BTA's alone. I have him housed in a 203g with sps/lps/nems/softies. He doesn't pick at anything yet (although i accept that he probably will) He is healthy and while has not been kept long term by me yet, he eats fine. There is sponge growth in the tank as well if he is really hungry he can eat it. He feeds off of pellets 3 times a day as well as formula 2 frozen, and my own food mixture that i feed the tank. He leaves the nems alone for now.
