gill problem
Charlie seems to be fine, but his gills have shrunk ? It's like someone has got a pair of scissors and cut them in half, i noticed a few days ago they were getting a bit black on the ends, now the ends are gone. The stalks are missing, but the filaments are there at the botttom. The tank temp is 19c, ammonia 0 nitrite 0 nitrate 40. ph 6.8. no one else in the tank seems to be affected. Charlie has only one long gill left. Do you think it could be caused by all the antibiotics he was given ? He is eating well, walks briskly, watches when we are near his tank. I would like some advice please, as i don't want this to become a major issue for him, after everything he has been through lately. Thankyou.
