yeah. I plan on getting some fish. The remaining mantis shrimps are elusive. The black sea urchin was less than a 1/4" (w/o spines) in diameter. It is now well over 1" in diameter. It just mows done the hair algae you see in the picture above. My wife named it "toro". She also named the sea cucumbers: vlassic, pickles,gerkin, (forgot the other one--I'm sick now so my memory is not good). I'll post new pictures tonight. Something is eating one of my gorgonians. Very tiny crustaceans. I'm bummed about that.
