I have 3 Jerdon's Baril in a 75g. I have noticed that two of them get a hard white "ball" on the tip of their mouths. I can not find any disease descriptions that describe this symptom and the fact that their is so little info on these guys around I am not certain that is a part of the genetics. The ball seems to bet bigger and smaller. It does at time seem to have skin hanging from it like a slightly opened wound. I have treated with API Super ick cure. Nothing changed. I then thought maybe hole in head or cotton mouth so I treated with API T.C. Tetracycline. The issue remains. The fish a happy, very active, colorful and have a good diet and are eating well. I would take a pic but if you have these fish you know how fast and uncooperative they are. Please help, I love them so much and being new to this I am a little worried I am missing a symptom. I will keep trying to get a good pic too.
