Last night my clownfish was fine, I did a water change, and this morning it has something hanging out of its mouth. It looks like a single brown thread coming out of his mouth, then it splits off on the end with some fuzzy things hanging off the end (this is the end thats not in the mouth). Wish I could post a pic, but I can't. My guess is some type of worm, but it doensn't look like a worm, and it doesn't move. The fish is starting to get aggitated with it. He's trying to scrape it off and then he's also resting on a rock some, too.
