dont pencil urchins eat corals? I had one eat the legs off a chocolate chip starfish, back in my early days.
They do, We had two in the display, one was banished to the sump for eating most of the smaller frag of GSP, and I caught the second one doing the same. however, it's still in the tank because for the most part it's been good. Some things have changed, IE we got rid of the lawnmower blenny because his personality changed in this new tank. We added a starry blenny, a scooter blenny, and a filiment wrasse. Also added a frag of zoas, a frag of frogspawn, a frag of purple rim monti, and a RBTA. Also, I recently aquaired a second 30G breeder so I will be making a new sump with that, the 29 gallon was just too tall to really do anything in. Also, I am knee deep in an LED build, and have all the components for a DIY reef controller.
