How big is the fish? What size tank is it in? How long has the fish been in the tank? What are the tankmates?

he is about 3.5-4 in a 60g cube with a pink tail trigger yellow tang a cleaner wrasse and a couple damsels. hes been in the tank for about a week

The math comes to 24"X24"X24" for 60g. Space could be tight and its pacing in the tank. When tangs and triggers feel crammed they pace back and forth (your case is up & down). Try a live clam on half shell and see if the smell of fresh clam can entice it to eat. The problem is your other fish will rush to the feast.

What sized tank did he come from? Krill is a horrible diet for a puffer.

i have a 10g i could move him to for the time being and try to get him to eat whats ur opinoin

I think he'd be even more unhappy in there. Is there plenty of cover in that tank?
