Poucupine puffers habits???
I just got one of these little cute guys and just wondering about thier habits. Mine stays at one end of the tank and doesn't swim aroung to much. I got him a few days ago and he's finnaly has eaten some krill. Now he's seems to have puffed up a little, just a little and is floating at the top of the tank. His fins and eyes are moving, is he resting now that he ate?
What else should I know about him?
