will the ghost shrimp breed because i don't go to the store that often. i am getting a fish soon that only eats live and i don't want to spend that much money feeding it. i had a shark come up to me in the Bahamas and try to bite me(i didn't even have a fish on me) and i had hit it in the face twice with my spear shaft witch is 5' long and the shark was about 10',.
