Hey everyone, I have a Stars and Stripes puffer who is knocking 3 inches right now and growing. My concern is that I have seen him puff up 2 times in the past 3 days. He was not provoked,bullied or spooked as far as I could tell...he just slowly started puffing untill he was huge then he shook it off. He has strong colors, aggresive eating/begging, quite active and shows no sign of disease. Could he just be getting his strech on? or is this indicative of a larger problem?
