Title says it all- Put a new zoo frag in the tank today, left the house for 30 min, came back, and Prick our urchin found the frag, and decided it looks better on him!
Yeah, I have a sneaking suspicion that our urchin (Spike), has eaten his fair share of our hermit crabs. I finally gave up on replacing them on a monthly basis. I think I still have a couple running around.
