My female betta has a patch on her side that looks tan in some lighting and white in others for the last 3 weeks. It is not super raised but is noticeable. The patch has gotten slightly larger even after both fungal and bacterial treatment. She is active and eats like a pig and does not show any lethargic symptoms. Her behavior has not changed all all since the spot has developed. I use aquarium salt regularly as well as give her a large variation in protein diets and it doesn’t seem to make her spot different. I have been increasing water changes to keep ammonia levels down. I’m not really sure what to do from here and don’t know if I need to be as concerned as I am.
