Help: Crab ID

[Kdocimo90]

I have these blue crabs that were sold as "blue porcelain crabs" but clearly are not. they are sort of spider-ey and burrow/dig themselves into the sand.

[Calappidae]

Mictyris species, or better known as Soldier Crabs. I almost never see these in the hobby.

Yes, soldier crabs. They are an inter-tidal species of crab. They burrow into the sand at high tide and come out at low tide to scavenge the sand on the shore. Without the ability to get out of the tank they generally don't live long.

I can't stop thinking how cool it would be to have a drop tankvdesign where an upper level was a beach...then your crabs could come out to scavange.
