You can not only keep a pr of stenopus, but other shrimp as well, I love stenopus (the genus of coral banded shrimp) and I keep prs. with cleaners, bumble bee, peppermint, harlequins and several species of hermits in my 24 gal nano. the only problem you have is pairing them up, I have never been successful in pairing them up in tanks. I have always collected prs and never had a problem. I see many prs available now both online and in LFS so you should be able to get a compatable pr, just make sure if you buy them online they are shipped in the same bag. I have lost prs by seperating them even just for the time they spent in the bags.
