you will need a container that you can see through, a net that will cover the top. container should be deep, 5 to 6 inches. dosnt have to be very wide, maybe 3 inches. lay net back to provide an opening into the container. place some fresh squid or clam (couple small pieces into the container and then just wait and when the shrimp goes in move net over the top and walla you have a shrimp. These shrimp are very active a night. maybe a net with some smelly food in it, when they enter pull up net. be carful not to snag reef rock or equipment. good luck, and very sorry for your loss. as you now know this is one shrimp that is not recommended for reef tanks.
Rhynchocinetes spp. (R. brucei, R.durbanensis, R. hiatti, R. rigens, R. rugulosus, R. uritai). Camelback shrimps (hinge-beak prawns) Feed on small polyps. very active at night. hope something here helps.
