Your pictures are getting very close to awesome and being able to be used for an ID. You might want to try posting that last pic and the others and see if Dr Ron can at least rule out hydroids or not.

That is a mithrax crab. Get rid of them if you get the chance. They will rip your sponges apart.Nirol said:Also, I have two of these red crabs, this one is very large (his carapace is about a half dollar) , but so far being a "good guy" and has left everything alone, but I am keeping an eye on him. He is very photogenic and poses allot.

Bob, Your urchin looks identical to mine. It came on my Keys rock also. It was the size of a pencil point(very tiny) when I first found it and is now quite large. It's spines are black and white in alternating bands of color. It wanders all over my tank and doesn't appear to harm anything.

Here is a picture of one of the hitchhiker corals on the TBS rock. Note the appearance of the "baby" in the upper left corner. Is this an offspring of this coral, or just a coincidence?

Yall got lucky as that urchin is protected and cannot be harvested, it is the long spine urchin from the Keys, eats algae off the reefs keeping them clean.
There used to be zillions of them in the Keys, then they all got some kind of disease and disappeared, thus the State made them illegal to collect a few years back.
They are on the rebound, and there are stocking efforts going on to replace them in the wild.
Watch out as they are sharper than any needle!!
