Oh Oh Oh... can I add some here too!!
First of all... Camelbacks have also been known to be nasty to coeral and polyps!!
Now to the beef: If you find that you have peppermint shrimp that do NOT eat aptasia, you could have a differing species all together...
This is a problem in the hobby right now. There are soo many "look alike" to the true peppermints shrimp that just don't have ANY interest in consuming aiptasia. It's really no fault of the LFS (for the most part) but of the distributors. You want to ensure that you are getting shrimp from the Western Atlantic, Caribbean area to ensure that you are getting Lysmata Wurdemanni.
There are TONS of stories of people buying shrimp only to find that they were Lysmata Rathbunae (found off of the Atlantic Florida coast) and not Wurdemanni. The tell all check sum between the two (besides the obvious dietary differences) is different tail markings. The Rathbunae has a dark tail, with no stripes, and a darker body.
Lysmata Californica, another imposter DOES NOT eat aiptasia. Also, for what it's worth, these other shrimp come from cooler habitat and their longevity in a reef system is questionable.
There are more 'look alikes' but I can't remember them off the top of my head right now. There was a great article in either Aquarium Fish, or Tropical Fish Hobbyist that goes into great detail about this. I forget which magazine, I get so many. If I find it, I'll post back here.
