I've never had to deal with FR, so I'm not entirely sure what it looks like. She and Luna had bit into each other tails, Luna is healing perfectly with a minor slit in her anal fin, (She also has a white spot on her side? I'm not sure if thats okay or not, I think its just her scale..) but Starlight's 1g got dirty pretty fast and that one day I had to work (I know its my fault, already feeling guilty) and now I placed her in a cup of clean water, and I noticed her anal fin is healing but instead of it healing up blue/white, its healing as blue/white with little bit of red, I don't think thats the color, it looks more like its irritated. I'm gonna get a pic of both, could she have fin rot? Should I get some AQ salt?
