Help Yellow tang not eating

[Snufflupagus]

hello all,

I have a yellow tang that isn't eating, and is looking extremely skinny. No matter what I do, he just doesn't eat, I think my other fish are just to quick and are eating the food before he even knows it's there. I started a little nano tank, I just have the filter and the heater going right now, would it be a good idea just to move him into that tank and see if he eats in there? There is no powerhead on that nano yet. Any help would be appreciated.

Thanks,
