HRP's aren't necessarily rare, but they are cool. I had some for a while. I've seen so-called HRP's that really looked just like convicts, blah. Mine looked very blue like the ones in your pics. Not quite as aggressive as convicts, IMO. I did keep mine in a mixed Cryptoheros set-up, wary of hybridization. Surprisingly, they were quite discriminate, choosing other HRPs over septemfasciatus, cutteri, convicts, etc. But if you keep them with just one other species that they can breed with, the urge to spawn will be too strong to resist, and they will hybridize.
