Crab ID please was on a chalice

[Drew589]

Found this little crab in the eye of a chalice possibly eating it, not sure, anyone know what type of crab it is?
It is very tiny, about the size of a small zoa polyp.
Took picture with my TG5 camera on microscope mode

That's an odd one. My first thought was that it looks like a pea crab, but not quite...

I'd remove it regardless, but interested to see if anyone else can positively ID.

It's gone already, didn't wan't to take a chance

Thanks for the reply

Gall crab?

Never heard of a gall crab? Just looked it up, could be one, thanks.

Gotta keep an eye out
