I got a Singapore angelfish a week ago for my 75g reef tank, since then it always hides and never eats prepared food but recently I started adding garlic guard to the food and he seems interested will he eventually start eating it? can he survive just picking off the rock? I know feeding can be a problem with this species. secondly he started to develop a taste for some of my corals will this eventually severely damage the corals? as I have a coral beauty that constantly nipped at a gorgonian but with no ill health effects on the coral, and can it be related with him getting hungry? thanks
