According to The Blood Parrot Cichlid Fish Is a Controversial Hybrid, the blood parrot is a hybrid cross between the midas cichlid (Amphilophus citrinellus) and the redhead cichlid (Paraneetroplus synspilus).MacZ said:Genetic analysis has brought to light they are not hybrids but a heavily genetically defected form of red devil cichlids (Amphilophus labiatus). But the genetic defects make most of them sterile nonetheless.
I guess my concern is that if it is a mutation rather than a hybrid and the males are sterile, how to they manage to continue the genetic line? I guess it would take a lot of DNA testing to resolve the issue.MacZ said:Right now I only got the citation at hand, but look for this article: Hanneman, E. (2000): The Blood-Red Parrot: Hybrid or Mutation? Tropical Fish Hobbyist 69 (4): 94-97.
