If it is FW it is a cray but they are often sold as blue lobsters, size and growrh rate depend on species, there are more than 500 species in north america alone. Worldwide they range from less than 1/2" to one from Tasmania that was recorded at over 30" long and more than 10 pounds. here are a couple crayfish links, http://crayfish.byu.edu/
