You have to watch out though. Over half the "halfmoons" my petsmart has up right now are deltas and there is no way they'll go HM. Actually most of the HM they had up were pretty crappy, there were 3 that I would have considered buying. The HMPK look nice but I wish they weren't touting them as "dragon scale" since not all of them are dragons, in fact none of the ones at mine were dragons.
