One of my younger crowntail bettas has developed cottony white fuzz on multiple ray extensions. Nothing on the body. He eats wells and swims around fine, but the fuzz looks like he swam through some dust bunnies.

Any ideas what it could be? Some sort of fungus? Treatment options?
Using salt at the moment.

Thanks.

my crowntails been getting these recently too. He only gets them on one ray at a time then they eventually fall off then come back on another ray in a few hours :( He's had them for a little over a week and it doesn't seem to bother him other than making his fins look a little ratty :(

Sounds like fungus.

I would net the betta. Hold the net in a bucket in the air. Pipette several drops of Methylene Blue onto the affected area. Let sit for several seconds. Place betta back into the tank.

Please note: Methylene Blue will stain so I suggest being very careful with this med.

Good Luck.

I wonder if crowntails are more susceptible because one of my other crowntails had it before too. The ray fell off and he is fine now, but this little guy has more on a few rays.

Thanks. I will have to get some MB then. Is it safe to directly drop the medication onto him?

Atom, Methylene Blue is safe to apply to the fish directly. This looks more like a fin rot. Try using Melafix as I had one of my veiltails contract the same ailment. Melafix worked for me :)!

That is true fungus. API Super fungus cure will work. Also Methylene blue as suggested. It can pop up on Bettas in the colder months, not uncommon.
