as in spiney box puffer fish? if the answer is yes.then Yes I do.depending on his size foods will vary.very small small krill and mysis shrimp .chopped squid is also part of a good diet.i suggest using a garlic supplimet also such as garlic extreme.presoak food in water with 2 drops garlic this helps keep fishes imune system strong.for larger boxfish puffers 4 inches and larger. I feed silverslides,krill,larger peices of squid, raw shrimp with shells on.as they get bigger they tend not to bother with smaller bite sized foods.they also like scallops and crab.hope this helps ps this is basicly the diet for all puffers.
