Since I started broadcast feeding my tank reef chili, my again lords have taken off. But, like stated the one pic is of a favia. It should be ok with just light...as most coral but feeding them will probably help. I used to feed my Duncans mysis, but it became a pain making sure each head only got one piece and that all 25 heads got attention. When I broadcast feed, all the heads on both my Duncans get to eat along with all of my other corals. The open brain that I haven't had for a week yet has started to show its tentacles to prepare for feedings.
