White almost bleached spot on my red mandarins goby

[Rsifuentes]

I looked in my tank this morning, and my red mandarin goby has a bleached out spot on his abdomen towards the back end of the right side of his body towards the back tail fin. But he’s still swimming around and eating as normal, and he is very healthy and plump. What could this be? I couldn’t figure out how to add a picture in here.?

I did add some new coral and rock that I did not dip first ‍

Edit: A picture would help.

Welcome to R2R! My purple tang just got something similar and I believe it is because he swam too fast into the live rock. He looks much better today than yesterday when it occurred.
