never in 8+ years of managing a lfs has a customer mistaken a blood parrot for a red devil. As for calling the devil something other than what it is, midas seems to be the common mislabel given.
Midas / Red Devil and the crossed MyDevil are mixed up all the time. Blood Parrots and King Kong Parrots as well but unless your living under a rock you can't confuse a Red Devil with a BP.
