I asked the lady there-- since he was too small for a kind and looked like their females, I played dumb and pointed this out. She actually thought he was a female too-- Especially in the store where he had his little fins all clamped shut. Btu she said they come labeled however they are, and they have to pay so much to get them, and then that's why they're priced the way they are.
Not sure if I buy that, but I thought it was worth a shot. The shimmery white halfmoon they had was pretty too-- but he looked like he'd been tail biting, and to my surprise I'm finding I really prefer PKs. Perhaps someday when I have more money I might try breeding HMPKs-- but that would be a ways in the future, after a lot of research and a new tank or two. xD
