My husband and I just brought home two Green Leopard Puffers. One is doing great, but the other is refusing to eat. We're feeding them exactly what they were eating at the pet store--frozen brine shrimp. They're both less than two inches, so our aquarium is not full brackish or salt water.
The picky fish is swimming normally and has a white belly most of the time. He does change to a very light gray around the back and between the white and the spots once in a while. There is a funny looking spot on his side--it almost looks like a popped blister. Could this be a parasite? I can't find any in-depth information about this kind of fish, nor can I find any pictures that show this kind of deformity.
Does anyone know what's going on with this fish? Or where I can go to get more information?
