I'm so frustrated. I have a 3.5" porcupine puffer and a 3.5" clown trigger in a 72g tank. Despite numerous attempts the porcupine puffer will only eat krill. I've gotten the clown to eat squid/clams/shrimp. My main problem is when these fish eat(especially the puffer) they make such a HUGE mess. The puffer will take a krill in his mouth and shred it into 30 pieces and only eat probably 1/2 of it. Little pieces of meat float all over my tank and despite have close to 2000 g/h circulation I still get spots where food collects. I'm tired of having to remove this food every time I feed them. I don't know why these fish can't eat the little pieces of food after they finish with the larger pieces. They are alway soooo hungry when I approach the tank so I konw that has nothing to do with it.
