I have almost 5-6 of these guys and they all look fat and happy...they come out only at night and are living in only one of the rocks...are these pest crabs?

Thanks

hard to tell but the first one in the vid looks like an emerald crab. they eat bubble algae. i have a couple in my 29g.

Hi there
It could be a porcelain But if green looking then I would say it's a emerald

They should be fine for a reef then?

Hi!
The first crab should be a Actaeodes tomentosus and the second one should be a Chlorodiella sp.

first crab is a xanthid. cool crab, not reef safe. 2nd is probably another gorilla crab.
