Should i keep this urchin or put him in my smaller 17 gallon? I had a small purple rock full of coralline algae on it, i dropped it in my tank and not even 2 hours later i see my urchin right beside it and the rock is paper towel white.. I wanted all my rocks to have algae, but it he clears it out like that..should i be worried?
