hello /an/
don't really lurk this board, but my sister's fish is looking pretty ragged and she's been too busy to do anything about it. i feel bad for it.
I got her this betta about a year ago, and I guess pretty recently it has this horrid white growth thing near its butt. Some sort of mold, perhaps? Any common betta afflictions you guys know of?
Any help appreciated, thanks. Pic related, tis quite blurry; was having trouble focusing on it.
