I got free zoas! What are they?

[ceruleanspiral]

I bought a polka dot crab at my LFS, it came with zoas on its shell. They are quite pretty but I don’t know what they are. Do these look like any named zoas?

Here is a better pic. Looks like yellow in the middle and green skirt. Darker red or purple between?

My crab switched shells!

I just epoxied the shell to my rock, heh. One zoa is kind of loose and one is hanging on it, like if I cut them off I could frag them (the two in the middle on the bottom)- but I don’t want to.

Is this a better picture?
