I don't know what this is, except I have been watching it develop from a small bump and has only gotten bigger. I was hoping it would go away as soon as I noticed it. There's no signs of scratch or darting, no fish have ich and haven't had any for a while now. I've treated with prazi pro and cupramine plenty of times in the past. I'm only mixing the right amount of salt with pure clean r.o./d.i. water. Nitrates fluctuate between 100-50 each day, as I've been trying to get the nitrate levels down. The trigger is eating and healthy looking otherwise and it's behavior is normal. Anyone know what this is on it's bottom lip area?
