My blue tang sure knows how to cause heart attacks. The first night as soon as the light dimmed to the moonlight setting he totally disappeared, couldn't find him with a flashlight, so overrode the light timer and a few minutes later he came swimming out from under a rock and looked at me like he was saying what do you want, I was SLEEPING..... Now if I inspect him as soon as he comes out to swim around in the morning, he looks like he has white spots on him until he swims for awhile and they fall off, he gets sand stuck to him being under the rock. 5 minutes of swimming around he is perfect and I saw it falling off of him.... Maybe the key is don't inspect him until he has been swimming for a bit....

This is pretty typical tang behavior. My current tangs hide while sleeping. I used to have a naso tang that would be covered in white blotches for 5-10 minutes after “waking up”.

Probably had to swim to knock the sand off him too

No, they were big blotches, like the size of dimes. Definitely his flesh changing colors. Probably some kind of defense mechanism while sleeping.
