I was wondering if someone had any suggestions for my Albino Tiger Barb. I have an 80 gallon tank with 9 Tiger Barbs (4 Regular, 3 Green, and 2 Albino), 1 Pleco, 1 Red Tail Shark, and 2 Pink Kissing Gouramis. It has been set up for a few months now. My little albino has been acting funny the last few days. I find him hiding in the corner with very figity movement. He did not eat today and his mouth is looking abnormal. It is as if his lower lip has gotten bigger. He has a bit of an underbite now. My levels are showing normal. Could this be a mouth fungus? I have dealt with ick before but that is about it.
