inch long, blackish hairy, milky greeneyed monster crab
 

it's residing in my red milli acro colony and i noticed it picking at polyp surfaces. anyone has an idea as to name or specie. it's cute and outlandish looking but i just might have to pluck it out and keep it in one of the acrylic cages inside tank.

I had one of those once....into the sump it went!
