Unfortunately I don't have a quarantine tank so I've had this Rosy Barb in about a 15 gallon bucket with preconditioned + tank water. A couple days ago I noticed it's lips were all big and swollen, and decided to seek your guy's advice.

I don't know what the heck the problem even is. The mouth is big, red, and swollen :(
I figured it may be a disease. It's in a 30 gallon with 4 other Rosy Barbs and 7 Lemon Tetras. I've had experience with chiclids and know this can happen with lip locking, but I'd never expect Rosy Barbs to do it, and didn't find any hint of it during online searches.
