Evening everyone. I purchased a porcupine puffer about 1month ago I'm having serious issues with him eating live food ghost shrimp to be exact. He won't eat frozen foods at all. I have tried silversides, clams on a half shell rottifiers. I tried not feeding him for a couple of days still didn't work he just watches the food sink to the bottom and he swims by it. I figured after a few days he would devour it but I guess I was wrong. Does anyone have any suggestions cause I am lost. He is so stubborn.
