Great! I'll add them tonight. Questions:
I'm guessing that the Red Reef Crab isn't dead in this picture, right? How the heck did he get on top of the urchin?
The urchin has little tube feet that it uses to move around. They pick up all kinds of stuff with them, mainly shells. If you notice there is also a live blue crab attached also.
What type of crab is the second one?
A bigger version of the crab riding the urchin. Richard calls it a Red Reef Crab. Some have refered to it as a Red Mithrax (sim. to an emerald crab, but red).
Which hitchhiker are you referring to in the third -- the tree sponge, or the other thing in the background? What is it (brain coral with tentacles extended for feeding?)?
Yes the brain coral is what I was refering to. The "tree sponge" is actually a green Montipora Digi that I put in later.
Thanks!
