I have two of these guys.  Proven aiptasia eaters, definitely not camel shrimp.  I got them to get rid of my aiptasia, which they did with gusto.  However, I have a smaller tank, and they eventually started picking at my frogspawn, so now they're in the sump.  Aiptasia is long gone.  Good news is they were really easy to catch.
$8 each.
ps - sorry for the crappy picture
