Common name: Takeuchi's Angelfish

General information

Takeuchi's Angelfish, scientifically known as Genicanthus takeuchii, is a rare and exquisite species of marine angelfish. This species is part of the Genicanthus genus, which is known for its members' distinct sexual dimorphism and the fact that they are planktivores, unlike many other angelfish that are known to nip at corals. The males and females of this species have significantly different colorations, with males exhibiting a striking blue body with a black spot on the flanks and females having a more subdued silver-gray appearance with vertical striping.

Care

Takeuchi's Angelfish requires a large aquarium with plenty of swimming space and a well-established environment with live rock for grazing. They are peaceful fish but can be territorial with their own kind, so it's best to keep them singly or in mated pairs. They thrive on a varied diet of meaty foods, algae, and marine-based flake and pellet foods.

Reproduction

In the wild, Genicanthus species form harems consisting of one male and several females. If a dominant male perishes, the largest female will often change sex to become the new male, a process known as protogynous hermaphroditism. Breeding in captivity is rare and challenging, but with a well-maintained and spacious environment, it is possible to observe their natural reproductive behaviors.

Habitat

Takeuchi's Angelfish is found in the Western Pacific, particularly around the Ogasawara Islands of Japan. They inhabit deep reef slopes and drop-offs, typically in waters ranging from 40 to 120 meters deep. Due to their deep-water habitat, they are not as commonly encountered as other angelfish species.
