I noticed for two days now that my clownfish won't close his mouth. This a fairly new tank and we've had it for about a month. We just recently added a new clownfish and two anenomes. One anenome is a green bubble and the other is white with purple tips. The bubble anenome was introduced first to the tank and later we put the other clown and white anenome in. The clownfish that has the problem recently noticed the white anenome and has been sucking on it's tentacles and all the sudden he won't close his mouth. What is wrong with him can somebody help? I was told to watch him and if he developed a white fuzz in his mouth then he has mouth fungus. I'm not sure but it does look a little fuzzy inside his bottom lip. Help please!
