I have 2 percula clownfish in my 55 gallon aquarium. I have had both of them for over 3 months. They have been doing great until earlier this week when the larger one of the two did no eat and i noticed a whitish growth in her mouth. She seems to stay in one location most of the time, but she still looks healthy and her stomach dosent apper to be caving in yet. She hasnt eatin since Monday. I was jsut wondering if anyone could give me some advice. I tried top get a pic but could not get a good one of the growth. Any advice woudl be great. All water paramaters tested out fine.
