New Stuff. No Clue

I got a couple new pieces of LR and coral today. Straight out of the ocean so I've got a bunch of living stuff.
Here goes:
Is this tiny crab reef safe? I already took him out but just wanted to make sure.


What's this brown slimy blob?


What's this green goo?


What's this feather duster like thingy? It doesn't have a tube more like a shell... Urchin???? This is it open


This is it closed.

 

I would have to say random goop ;D. Sorry dude, no clue but what does the crab look like? pointy pincers or rounded?

 

For the crab, go here Crab Hitch Hikers and scroll down to the last section and see if it matches any of those crabs. I can't really tell from the pic.

 

The brown slimy blob looks like what the pollips grow on.

 

The pincers are pointy.

Thanks for the link stepho. But unfortunately I really can't ID it.

Ok good. I didn't know if I should scrape it off of the rock or leave it on. I think it's safe to leave it on there right?

 

Pointy pincers are usually bad in a reef, might want to consider throwing him back. BTW it's legal for you to harvest things from the ocean?

 

Well, not 100% legal but it's allowed in moderate amounts from where I took them because it's not a protected area of the ocean. Also, I can't break off pieces. I can only take pieces that have already been broken off. That's why the pieces of SPS that I have, More than 80% of the coral is already dead and white before I harvest them.

 

That is really cool. One reason I could never live by the ocean . There is no way I could resist that much temptation!

 

I hear ya. I'm tempted to go in the protected ares to get the good stuff but I can't:-/:
Any idea what the little feather-like thingy is?

 

I have no idea. Any chance you can get closer? My closest guess would be a Christmas tree worm...
