[ame=http://www.youtube.com/watch?v=J18y1PycIFk]Crab HD kinda macro - YouTube[/ame]

any ideas?

the close up starts from like 1:30 or something...

 

Stone Crab?

 

nope... stone crab has black tips on his spinsers... This one doesn`t... i have stone crab in my refugium, this one is way different, and has green spots on his spinsers/hands

 

Looks like a xanthid crab to me. They come in many different colors. IMO, take it out since it may become a problem when it gets bigger.

 

My friend, You should know about me one thing...I do not take out crabs, due to the reason I strongly belieave that if the crab is being fed it is not going to attack anything else.... The only thing i have removed from my aquarium are the FIng bristle worms

 

Xanthid coral crabs form symbiotic relationships with coral. They live in and feed on the coral in return for defending it from more voracious predators such as crown-of-thorns starfish. Although the crab itself eats some of the coral's polyps, there is no evidence to suggest that the coral is harmed by this low-key feeding. In fact, corals with crabs associated are generally more healthy than those without, probably because they do not suffer large-scale attacks by more voracious predators.
