I need a little help. I bought a porcupine puffer a couple a days ago. I brought him home and he seemed to be happy swimming around and investigating things. The only problem is that I can't get him to eat. He ate a piece of squid but spit most of it out. That's about it, he'll look at the food but wont go after it. The only thing that really catches his eye is the yellow damsel I have in there. He seems to really want that. I made sure he was eating before I brought him home. He ate at the store. Any ideas?
