Etymology: Coelotilapia: "The genus name Coelotilapia Mayland, 1995 was introduced in a popular aquarium book, but it is not available, because it was treated as a questionable new genus, but was described as a generic name under Tilapia and not used in the combination Coelotilapia joka. The name was chosen to refer to the cave-breeding habit, but Mayland refers to the Latin word coelestis, which mean celestial. Very likely he thought of the Greek word ‘koiloma’, which means cavity.".
