So i'm actually posting this on behalf of my younger sister (she's 10) who called me earlier this evening to ask me if it was okay for her betta, Anabelle to have "white things" on her gills. She said that they didn't look cottony, but that there were white things on her gills that she'd had for a few days and that she hadn't eaten in a day or two.
My first though was columnaris, but since she said it isn't cottony or puffy, I'm thinking that it might be a fungal infection. I told her to pick up some JFE/JFC tomorrow from our LFS, but I just wanted some other input on it. The tank is a 2.5gal with a hydor mini heater, aquarium salt and a whisper 3i filter which she inherited from me, not sure of the water params or water change schedule. I told her the water needs to be changed at least 50% weekly, but I don't know that she's following it.
Also, I am at college 4.5 hours away or else I would post a picture of Anabelle.
