So, im looking at the pbb today and i notice he has some fraying on he fin. None of the fish mess with him at all. I watch them like crazy and ive never seen anyone bother him.
Im confused as to how it could be fin rot because i just tested my water and everything is fine 0 ammonia 0 nitrate and 0 nitrite. Just did a water change 2 days ago and i was having problems that i addresed in another thread. So what could it be?
