I just got a Halloween urchin for my 75gallon mixed reef tank. When I got him home, acclimated and in the tank he had more white hairs on him then he does today. I am wondering if this is normal just from traveling/acclimating stress? I currently have a standard white/gray pin cushion urchin in the tank (12mo+) doing fine. Tank is 2years old.
I am just wondering if I should be worried. He is moving around and seems fine. Seems odd that he has lost some of the white spikes/hairs.
