i have always found arrow crabs extemely interesting
i have wanted one for some time now
i have heard once they get big enough they start taking down fish
i wanted to put one in my 10g
i don't know much about them
so could someone give me some information?

would it be ok in a 10g with 2 or 3 SMALL (1"-2") fish?
