Odd "growth" around clowfish mouth
While feeding today I noticed a "growth" around one of my clownfish's mouth. He doesn't seem to br able to close his mouth. I dont know if he is eating or not. He is acting fine (no heavy breathing or having trouble swimming) however he is staying towards the middle of the tank and not adventuring like normal. I have had him for 2 and 1/2 months. I did add 2 royal grammas 3 weeks ago and have seem no aggression or sign of disease in either my clowns or royal grammas. I'm lost on what it could be whether it's an infection, disease, parasite, or a stress induced thing.
Water parameters- pH 8.0 nitrite 0 nitrate 0 ammonia 0 salinity 32 ppt
I can't figure out how to attach a picture
