Had my blue spot puffer around a month he is housed with a maroon clown, chromis, valentini puffer and green spot puffer. He was a very good eater up until a couple days ago. The other 2 puffers are fine. The blue spot stays near the top of the water a lot now. I haven’t seen any aggression from any of the fish towards each other. I can’t tell if he’s having any beak issues. I drop half a clam in once a week and the puffers demolish it. He looked nice and healthy and now I can tell he’s lost some weight.
