Introduction
Apistogramma borellii is a small South American cichlid and a popular aquarium fish. It was described by British zoologist Charles Tate Regan in 1906 as Heterogramma borellii. It’s commonly known as the Umbrella cichlid. For many years the cockatoo dwarf cichlid A. cacatuoides was traded as A. borellii whilst A. borellii was incorrectly sold as A. reitzigi. This confusion lasted until Sven Kullander published a revision in 1983.
