This morning I was working near my tank, the lights were off and I see something moving near my glass I turn the lights on and low and behold there is an urchin in my tank. I never purchased an urchin and the last time I added any frags to my tank was over 8 months ago.
So, is it a good one or bad one to have in a reef tank?
Another shot.
