Lionfish not eating

[Nihoa]

if you wanted to try a live food like searescue suggests ghost shrimp and mollies are a better choice. that said, in an emergency and just to get him back on food most people would agree that a goldfish or two isnt going to be problemtaic in the long run.

do you think there is a possibility he was overfed? ive read that if they gorge themselves they can have trouble passing large quantities of food and it can plug them up. if thats the case i dont know what much you can do about it.
