I wasn't sure where to post this, so sorry if this isn't the right place.
About a week or more ago, I saw a white puffy thing on my betta's lip that would sometimes go inside his mouth when he ate. The next day it was gone, but I have started to notice that it looks like his lips aren't like they should be. I wouldn't exactly say that it looks like they're being eaten away, but they don't look normal. I guess maybe they don't stick out like they should. He acts fine though. I have put aquarium salt in the tank, but not a lot because I read that cories don't do well with it, and I have one with him as well as neons.
