Copperband Butterfly Won't eat

I have an aptatia problem and so I thought I would start off with a cb. I know they are not 100% reef safe but I read that most people have good luck with them. I have had it in the tank for 4 days and he just picks on the LR and not the aptatia nor has he eaten any of the frozen food I bought from the LFS. I heard clams were good but I don't know where to start in GF. Thanks for any input.

I've heard they are partial to worms, bloodworms, blackworms, whatever you can get, even if it's freshwater fare it's probably better than not eating at all. Live would be best but hard to find. What foods have you tried so far? He might still just be settling in but with those it's best to get them feeding ASAP.

They are VERY picky eaters... Typically they'll take care of the aiptasia then just fade away...

As GP said try some different worm based foods and see if they like it. have you tried using any garlic treatments for the food?
