Lysiosquilloids are commonly called tiger mantis because of there horizontal stripes. They are totally different that O. scyllarus and require very different housing. Lysiosquilla are burrowers in sand. They are not active and do poorly out of a burrow. They do form monogamous pairs in burrows, but unless you are sure that you have a male and female, you are courting disaster putting two together.
There has been a flood of Lysiosquillina being imported in the past month. They are fairly easy to collect from intertidal sand flats and usually are sold for food for a few cents a piece. Someone has figured out that they are fairly exotic in the aquarium trade and can bring a high price.
I have posted detailed instructions for keeping L. maculata on this site. If you can't meet the husbandry conditions I've outlined, I would suggest that you should pass on these animals.
