Hi, I joined this forum about 2 months ago when my betta contracted fin rot and I didn't know what it was. I treated him with API Erythromycin and Aquarium Salt for 14 days and got him a better environment (see below) and he got so much better. But now he is looking a little weird again. The only symptom I can really see is that he has white stuff, I would almost call it dandruff, coming off of the 2 long skinny fins under his head. Is the fin rot back? Or could it be something else? Or am I worrying over nothing?
