Cool Crab

[FunWithFishes]

So I have a small 10g set up in my office that I stood up in January. I got my live rock from Tampa Bay Aquatics, which is still producing new hitch hikers even after all these months.

A few crabs made themselves known pretty much immediately. But Monday I started noticing the little guy below.

I thinks it's a porcelain crab, but wanted your opinions.

Definitely a porcelain crab from the Petrolisthes galathinus complex; it looks like it probably actually is P. galathinus in this case - neat hitchhiker to have!

I have this guy - who started off as a much smaller purchase (can't remember the name) - he is now large and an algae eating machine. Might nip at smaller fish but so far all are ok.

Oh wow, gets a pretty good size. Gorgeous though!

There are plenty of porcelain like crabs that are free living and not associated with anemone.
Along the Texas coast, there are similar crabs, filter feeder also that are green in color. These crabs are in the same family, if not genus.
The green one is P. armantus, free living invasive species from South America.
