Not sure if I'm dealing with ick, but my blue betta Pierre seems to be suffering from some sort of fungus. He has white fluffy/feathery appearing things hanging on him. They arent very big but they are definitely new. Started noticing it within the last week or so. He has resorted to rubbing on his rocks as though he's trying to get it off. He isn't covered with them; theres only 2 or three of these hanging from him. They're fairly small, but are not salt-like in appearance the way ick is usually described. He also is not "sprinkled" with them.
Any ideas? Is it ick or something else, and how should I go about treating it?
Tank is the betta bow 2.5 gal., temp is about 80, ammonia, pH, and nitrate sensors are normal/safe. Water changes are done about every 5 days.
I can try to get a picture, although he's never been one to sit still.
Thanks in advance!
