Not that I'm going to do it but I'm just curious. Wondering if casual people do it or just special breeders? And if so would you use a female RD? I'm assuming a male would kill a female Sev.
from article linked said:Controversy even exists over their parentage. The most likely pairings are the Midas Cichlid (Cichlasoma citrinellum) and the Redhead Cichlid (Cichlasoma synspilum), or a green or gold Severum (Heros severus or Cichlasoma severum) with the Red Devil (Cichlasoma erythraeum). I personally believe many of the "calico" Bloody Parrots seen on the market are from the latter pairing. It is also possible that Amphilophus labiatus, or even Archocentrus species are used in creating Bloody Parrots. Regardless of their heritage, one thing is certain - they do not exist in nature
