I have a spinney boxer puffer I think. Anyway I was watching the tank and it looked like for no reason he just puffed up but then I saw the big turd fall to the bottom of the tank. It later ate a bunch of shrimp. I can only get it to live fish or cut up shrimp so it gets the shrimp the most often. I have heard it is not good for them to puff up much. Dose this cause any problem to the other tank mates?
