Growth on Maroon clown
 

Hi,

I was feeding my tank this evening and noticed a white growth underneath my clown's mouth ( chin). There also seems to be a white patch near her left fin, on the underside. She has been in the tank for about a year, and was quarantined before she was put in. Im pretty sure she is wild caught if that helps.

I'm sorry for the fuzzy images, they are taken with my phone, and the colour is way off ( Black sand looks pink)

The pictures were too blurry to tell what it is. But look up lymphocystis on the net to see if it matches the growth on your fish. Another possibility is fungus though marine fungus is quite rare.
If it's lympho then not much you can do. Keep the water clean, feed high quality food, reduce stress and the fish will heal.
good luck!
