I have a chocolate tang that’s been in my tank for a few months now. Recently he has been scratching on the rocks and sand so I’ve been keeping an eye on him. And now he has white spots that are more visible in the blue light. In the white light they almost look like pieces of fuzz. From pictures online it doesn’t look very much like it but I feel like it is so I don’t know please help me. I’ve never dealt with this stuff so I don’t know what to look for or any of that. Thanks for the help!
