Mespilia Globulus

AKA the Blue Tuxedo Urchin

Picked this little guy up tonight hoping he will clear my reef of the hair algae problem.

These little guys like to pick up pieces of rubble or small coral polyps and stick them on their backs as a way of camouflaging themselves.

Also dropped in two little peppermint shrimps to eat up all those bad aiptasia anemones in the refugium.

I can tell the water parameters are off so this weekend I'll do a big 30% water change and se if I can't get the tank back on track.
