Hi Guys, I was just at the LFS today and they had a "multi coloured urchin". I'm finding little to no information on him but he looks very similar to a tuxedo urchin but more brightly coloured (same coloured bands as a tuxedo). I do have a reef tank with small fish and inverts as well and need...

Yesterday I bought a pink rose sea urchin and I'm starting to get worried. I drip acclimated her ( yes I'm saying shes a girl) for 3 hours then put her in the tank. I was super excited when she immediately started cruising :) This morning when i woke up I checked on her and she was shedding some...

So... these 2 little guys crawled out of the live rock I started my tank with back in October. Started out as tiny microscopic little bug looking critters, and lo-and behold, here they are. I am guessing I got pretty lucky by getting 2 baby urchins from my live rock. Anyone able to identify...

I set up my 55 gal tank about 8 weeks ago. It has about 80 lbs of live rock and is starting to show some real life. The clean up crew is munching away but I just noticed that I have some hitchhikers which I am not sure I should keep. So far I have seen two small blue-black urchins about the...

I have had a pencil urchin that ate half of a huge feather duster and most of my corraline algea. Although he was a bad boy (lol) I still thought he was the coolest thing, but since I was starting a reef I had to get rid of him. On many websites I see pencil urchins classified as not reef safe...
