Let me know how it works out for you. We love our puffer. In fact, she is the center of the tank. I have reef clams and she has never touched them. She knows her food is clam on a half shell. They are also very smart. She can make sounds with her teeth.i have a uv let me find it i'm going to do hypo and uv see if something gets better i'll keep you guys updated. i can take the e puffer out of this qt to a different tanks see if that helps but i doubt ut since he's so infected
