Please see pics. This is big al. He is a 6" mbu puffer. I have had him for almost 4 years now. He never grew : (. He is in a 350g system right now. Anyways, I noticed these growths on his topside today. One is like a raised open sore. He has never had this before and I'm not sure why he just got it. I haven't introduced any new fish in months, and I quarantine all new arrivals for 6 weeks before adding them in. Water parameters are pH 7.6, nitrate 10-20ppm, nitrite and ammonia are 0. Tank is on a 24/7 drip system. None of my other fish have any symptoms. Any idea what this is and how to treat? He just ate some shrimp and a clam and moving around like nothing is wrong...good sign.Sent from my iPad using MonsterAquariaNetwork app
