Crab ID please

Never seen these before:

had a tub with liverock sitting in my garage for about a year - temps changed from 42F to 94F (if I can trust the digital thermometer on it, LOL) over the course of that year.
Salinity must have fluctuated like mad as I topped off with 5gallons every 2 months or so - the tub only holds 23 and most of that were rock,

I emptied it today to move ALL my rocks to one dedicated holding system and found two of these boogers:

Almost looks like a Pocelain. 2nd opinion?

I looked up pics online - you're right!

Those are fun crabs because they feed using what look like "fans" on the end of their arms. They hold them out in the water column to collect small particles.

One of my favorite additions!

It's amazing that they made it through the temp and salinity swings. Great Find! :thumbs:

Hmmm... Petrolithes galathius perhaps? It's sometimes hard as most pics as taken under aquarium lighting because the shell can flouresce and makes ID difficult.

Nonetheless, neat find!
