Hi folks. My tank hates me, though I love it.. So fight I will. My clown fish has his mouth open and its almost white.. He is normal colours.. params are normal 1.023-24 salinity.. I've looked around trying to diagnose this with much failure for everyone just answers what params or some foreign parasite that nobody knows about so here I am hopefully I can get a decent opinion. Well he isnt breathing fast or hard..and his mouth is just swollen and open.. He is hiding in the back of the tank and I'd love to find out what is causing this issue.. if it is a mouth fungus or bacteria infection or maybe he had it out with one of my shrimp... Anyways any info is good info... I'll see if i can get my webcam to focus on the little guy for a picture..
