Seems to be picking at rocks, likes some zoo's and xenias from what's been happening in the tank...i cant rotate you will need to edit before uploading :) what corals is it eating?
In Terms of the photo it is the right way up everywhere but then rotates when I select insert full size image :( The ones of my MP10 rotated differently for some reason. but then others like FTS work fine.... Hmmm No idea :(
Kind of want to keep the crab. he is cool looking... But as soon as he has a fish for dinner... He is gone (if I can catch it) No idea on the photo...If you right click and open in a new tab, it turns it the right way. Go figure.
Cool looking crab, shame it is eating your corals.
