has anyone kept a beaked pufferfish?

can they be trained onto feed foods?

Yes and they are a very fussy eater,in that they need some corals and sponge in there diet to sustain them on average,but as with any marine creature there are exceptions to the rule.these are a very pretty fish,and they are of the filefish family,related to the triggers and leather jackets,there name is oxymonacanthus longirostris,found down most of the queensland coast.

If i remember right a similar thing was said to a guy called steve about a semi ( blue angelfish),9.9 times out of ten it's all instincts and thats all there is.Some have very strong coral devouring instincts one or two have very litle.Luckely the flame is one of the last.
