Different types of decorator crabs?

[crustaceanenthusiast88]

I saw a decorator crab at my LFS and thought he was the coolest thing. I tried to do some research when I got home, but then found out there’s different types of decorator crabs. I saw spider, sponge, and even arrow decorators. Can someone please explain the difference and which ones tend to be the coolest/prettiest? Or easiest to keep? Thank you

The difference is what species of crab it is and what they prefer to cover themselves with.

The coolest/prettiest is really subjective, but I'd probably suggest to avoid sponge decorators, as sponges (not the crabs, the actual sponges they carry) are often incredibly difficult to keep.

Other than that, I'd suggest just finding the one you think is the coolest/prettiest, researching it to see if it can fit comfortably in your tank, and going from there.
