Hello I'm currently deployed and my wife sent me these pictures of one of my clownfish with large spots on it and is resting at the bottom of the tank alot. Im fairly new to the hobby and would like help so I can help her. She is really worried about killing my tank while I'm here overseas. Any help would be greatly appreciated and relieved. I appologize for the blurry photo it is the best we could get woth our phones.
