I recently got a BT Urchin and I noticed today that it has dropped some of its spines and is not looking so good. My SG is 1.025, Ca 450, Alk 8.3, ph 8.0, temp 80-82 and no phosphates, nitrites, or nitrates. The first seven days or so it was moving around on the rock and sticking things to itself but the last two or three days it has moved on to the black overflow box. I was very careful and moved it back to the rocks, it was stuck but I am begining to question whether it is still alive or not. Any help would be greatly appreciated. Thanks
