Hi All. I have had my dwarf lionfish for 8 months now and he has always eaten well (frozen foods). Over the last week though he cannot swallow the food. He takes it in and the battles for about 30 seconds before spitting it out and sonetimes trying again on the same piece. He is about 3 inches long and the pieces are relatively small. May small fingernail size. I am desperate, can anybody offer any advice please.
