ive had these two clowns for a little bit about a week or so, and ive noticed one has been getting what looks like nippage on fins, the other didnt seem so aggressive to where i observed actual nippage but i assumed it was part of the proccess of who become female etc. but today i woke up and found theyre getting worse and starting to get this white rim along w them not really using one of their fins, not clamped but also not really being used. what should i do?
