Try soaking some food in garlic juice first.

I'll say it once again, probably not for the last time - fish have to be fed at least 2x per day to be healthy. Here's what Bob Fenner says, more than once in things that he has written and in another writing he recommends 3x per day!:

The 'secret' to maintaining these fishes is to provide foods often and varied. Sorry, I can't help myself in re-emphasizing this point. Get your marines to eat quickly and offer algae, different foods in small amounts as frequently as practical.
