I noticed a cauliflower like growth on the underside of my clownfishes "chin". It is a dull white/gray. He doesn't seem to be bothered by it, he eats like a little piggy, swims normally, snuggles in the anemone. I quarantined him and started treatment with Furacyn. It is now 3 days of treatment and no changes. What is going on and what else should I be doing? :?
