How can i tell if my sea urchin is died?

Question

i put him in my tank and everything else is good but he won,t move is this normal or is this bad and how to i tell if hes dead?

Answer 1

Well, first of all, do you give him algae to eat? and if so, does the amount of algae change? Sea urchins usually move, and I looked all over the internet just for your question, so be thankful I know allot about animal behavior. Now, I'm no expert on sea urchins, but i figure he is either sick or dead. I'd look up vets in your area that specialize in marine biology, just to be safe so you don't bury a sick sea urchin alive and condemn him to a slow and painful death.

hope this helps,
