The blood parrot cichlid (or more commonly and formally known as parrot cichlid; no binomial nomenclature) is a hybrid of the midas and the redhead cichlid. The fish was first created in Taiwan around 1986. Blood parrots should not be confused with other or salt water parrotfish (family Scaridae).
Because this hybrid cichlid has various anatomical deformities, controversy exists over the ethics of creating the blood parrot. One of the most obvious deformities is its mouth, which has only a narrow vertical opening. This makes blood parrots somewhat harder to feed and potentially vulnerable to malnutrition. Some cichlid enthusiasts have called for their removal from the market and organized boycotts against pet stores that sell them.
Blood parrots are often bright orange in coloration, but there are other colors that they can have naturally, such as red, yellow or gray. Other colors may be produced by dyeing the fish, which can shorten life expectancy. Some fish have been injected with a colored dye by the breeder. Another modification, generally considered inhumane by enthusiasts, involves cutting the tail while small which causes the fish to grow into a heart shape and are usually sold under the name of heart parrots. As the press has brought this practice to light, the majority of fish stockists will no longer sell these modified fish. Adult fish can grow to a length of 8 inches (20 centimeters) and reach an age of 10 to 15 years. Various breeds of blood parrots have been developed such as the king kong parrot which typically vary in color from red to yellow. They have fully functioning mouths with less of a nuchal deformity and grow larger. They are usually considered more valuable than blood parrots.
As a result of hybridization of the parent species, the fish have several anatomical deformities, including a beak-shaped mouth that cannot fully close, which they compensate for by crushing food with the throat muscles, a deformed nuchal, and compressed vertebrae. Some commercial foods have been developed specifically to be easy for blood parrots to ingest, and recently some blood parrots have been selectively bred to be able to completely close their mouths. Blood parrots sometimes can have deformed swim bladders, causing an awkward swimming pattern; and unusually large, and often deformed irises.
