Symptoms and Treatment
How has your betta fish's appearance changed? White fuzzies on the crowns of her dorsal and ventral and anal fins
How has your betta fish's behavior changed? same as always
When did you start noticing the symptoms? this morning for sure, questionably on the ventrals yesterday, but i thought it was just crud she'd picked up from the bottom of the seemingly clean bowl
Have you started treating your fish? If so, how? Not yet
Does your fish have any history of being ill? no, other than big belly
How old is your fish (approximately)? I bought her about 3 weeks ago, she's less than an inch without her tail added.

SO this is what I see this morning. It's not as noticeable when she's not backlit, but it's clearly visible when she is. And no, the water isn't actually cloudy. I changed it 36 hours ago. And will change it again in about an hour, after the kids are fed.

My apologies for the picture quality. She's incredibly camera shy. I can barely get her to stay at the front of the bowl for pics.
