Common name: Bleeker's parrotfish

General information

Bleeker's Parrotfish, scientifically known as Chlorurus bleekeri, is a vibrant and colorful species of parrotfish found in the Indo-Pacific region. This species is named after the Dutch ichthyologist Pieter Bleeker and is recognized for its striking appearance and significant role in coral reef ecosystems. Adult Bleeker's Parrotfish exhibit sexual dimorphism, with males displaying more vivid coloration and larger body sizes compared to females.

Care

Bleeker's Parrotfish require large, well-established aquariums with plenty of live rock and space to swim. They are herbivorous and need a diet rich in algae and marine plant matter. Due to their feeding habits, they can be beneficial in controlling algae growth in the aquarium. However, they may also nip at some types of live corals, so they are best suited for fish-only or reef tanks with caution.

Reproduction

In the wild, Bleeker's Parrotfish are protogynous hermaphrodites, meaning they are born female and can change to male later in life. This change is often triggered by social factors such as the absence of a dominant male. In the aquarium setting, breeding Bleeker's Parrotfish is challenging and rarely observed due to their complex social structures and spawning behaviors.

Habitat

Bleeker's Parrotfish are commonly found in coral-rich areas of lagoons and seaward reefs. They play a crucial role in the health of coral reefs by grazing on algae that, if left unchecked, can overgrow and suffocate corals. Their natural distribution spans from the Red Sea and East Africa across the Indo-Pacific to the Line Islands and Tuamotu Archipelago, and north to the Ryukyu Islands.
