Got a great box of Kaelini Tonga LR from a fellow reef central member. On one of the rocks was this...
Looks like some kind of sea urchin... Is it good or bad? Also this is a new tank and this LR is the first thing I have added to it so it is not cycled. Any advice on how to try and keep him alive?
