    I recently adopted a female betta fish from a family member and she is currently in a sorority with two other, younger females in a 10G tank. They get along well and everything seems good in that regard. A couple of days ago I noticed that this female had a (relatively) large, light-colored bump protruding near her eye. It seemed to appear overnight. She is still eating well but might be a big more lethargic than usual. The size has stayed basically the same, maybe it is has gotten a bit larger. The other two fish in the tank have no signs of anything, are energetic, and eating well. I am not sure on the exact age of the affected fish, but she was originally bought by the family member well over 1 year ago. Does anyone have any thoughts? (Other relevant info and pic below)
