I'm not a fan of pellets. I find they get eaten right away, then they absorb water and expand, sometimes blocking up the fish. Sometimes it would pass, sometimes not. Unless the pellets are really tiny, I wouldn't use them for this reason.
He might be just 'full' ... or the pellets might be causing a problem. About all you can do is watch and wait - there's no Pepto or Ex-lax for fish, I'm afraid
BTW - are you aware that the panther grouper grows to 3 feet? Hope you've got a big tank or an exit plan for it - I've got one that was given to me after it outgrew a 225. It's in my 1000 now but will likely outgrow that too.
I can barely afford to feed the thing!
He eats better (and more) than I do!
