I am now aware of the crab being no good but still unaware of why???
Will he eat everything, fish, shrimps, worms, anemones, corals, he only comes out at night ??? why is this crab so bad?

[Stingray]

This is the crab that most closely resembles the one in my tank

Actaeodes tomentosus Guam 782-12

Could even be this one only purple in colour, same body, leg shape

Liomera stimpsoni Guam 456-26

Its definately a Xanthidae crab of some sort...

COPPIED FROM THE CRAB ID PAGE



The Xanthidae Crabs (link - extensive photo gallery) None of which can be considered reef safe and can be the most destructive of the crab types. While very small, they seem to pick at algae on the rocks, but just as with other crabs species, once they gain a bit of size, their ability to pick off and eat any number of invertebrates and corals also increases. They also have a bad habit of enlarging their hiding places within live rock and will, in due time, weaken the rock considerably.
