Help determine the type of crab

[yame1324]

Hi all, I'm buying a couple hermit crabs in a couple days, but I don't know what species they are. Maybe someone can help me to determine their species from the description? (I don't know how to attach a photo, sorry). They are small in size, their shell is the size of two phalanges of a finger, they have a light gray body, gray legs and light orange antennae. I also want to know if they will grow or not..... I just couldn't identify their species and I don't know if there are very small hermit crabs that stay so small for life.. The seller told me that this is a type of coenobita, but I do not know which subspecies it is specifically

Species ID is usually done by looking at the eyestalks and claws. Are the eyestalks tear-drop shaped or more cylindrical? And what color is the big claw?

Oh, it seems this is the first option. Their eyes seem to be like an inverted tear or something like that. I will try to send a photo

I would say that's C. rugosus.

C. compressus can look really similar at that size - and are usually found in intact nerites like that - but their coloration tends to be intensely strong blues or greens.

JoeHermits, I love the field guide!
Saving this page in case I ever run into one of those other (i.e. non-clypeatus) crab species...
