The "Hystrix" they're listing isn't a Hystrix - you can tell from the picture but if it was a Hystrix, it'd be twice the price or more. Jeff Rapps has 'em listed at US$250 each.
The "one male one female" Retic another guy ordered from them turned out to be two males.
Think hard about using Aquabid for rays without at least checking in on the ray forum here to see if any given seller will actually be selling you what you're looking for. A couple of the ray sellers that sometimes post on Aquabid are guys who post in the ray forum - these are the guys you want to be talking to.
A bad first experience getting the wrong ray from the wrong people would really suck.
