I ordered a Rock Boring Urchin from Reef Cleaners the other day (and other critters). It was delayed an extra day at the PO (long story, all PO's fault, not John's). When I finally got it, water was very cold (there was a heat pack, guess it didn't last too long). The urchin had a lot of broken spines in the bag. After floating and acclimating, it moved immediately into a crevic of a rock. This morning, it moved a bit, but lost a lot of spines. I am not sure if these were the ones that were broken in shipment or not. Is it normal for an urchin to lose much of its spines during and after shipping? How long does it take for them to regrow its spines? And I also got a Brittle Star.. it's not moving too much. I know it's alive because it did move from here to there, but otherwise, it's very still with its legs hanging out of the rocks. How can I tell if its healthy? is it normal for them to be still much of the time? I am sure both critters are very stressed from the cold water and shipping, I need to give them time, but I want to know what I need to look out for! I've never had an urchin or a star of any kind before, all new here!
