well at first i thought it was a mantis shrimp. but after luring him with some food it looks like some crab. he is living in the rocks. he almost looks like a fiddler crab.he is red and white, spider looking with a big claw. any idea on what he is. i can't get a pic b/c he is in a hole in the rock.

very few crabs are good so IMO i'd evict him
Even fewer crabs with really big claws are good. My little emerald, small as a dime, can crunch coralline with her little claws. I'd hate to think what a larger one could do.

he looks like an emerald crabbut he is rust color. he has the same size claws as an emerald. Ihe has been in there for a few months now and no problems. he is very shy and lives in his little hole. I have an emerald crab who is bigger then a quarter and he is fine, never bothers anyone. I can't get a pic, the crab is small. the size of a dime at the most.

There is a species that is similar to the green emeralds that is completely harmless.
