ID's again. Please help !!
 

Here I have found this feather (hpefully no harm) and the crab (Keep sitting on my corals at nite, hope he won't see the corals as his diner :sad: )
Please help me ID them please.
Thank you in advance.

1. hairy crabs are usually bad news -put him in the sump
2. feather duster/tube worm, harmless filter feeder

Looks like a common hairy crab or a brown hairy crab.

Bad.

however,

Don't always go with the "hairy crab = bad" rule.

Many emeralds have hairy legs. Some closer species to the emerald that are black/ brown marble in colour are hairy as well (name escapes me)

First thing you should look at is it's claws. Sharp and pointy tips on the claws means it tears away meat, little suction cup/pad looking things on the tip of the claws means it rips off algae. Suction cups= reef safe.

In my experience though, if the crabs is hungry, it may nip at small polyps on SPS, regardless of the species.

Thanks guys. I'll catch him tonite. And thanks to my wife, she was the "founder" of this hairy guy. Ehehe
Oh, the feather, I found 1 and now 2, dont tell me this thing grow that fast :question:

Thanks,
