Common name: Bullethead parrotfish
General information
The Bullethead Parrotfish, scientifically known as Chlorurus sordidus, is a vibrant and active member of the reef community. This species is known for its remarkable ability to change colors and patterns throughout its life stages, which is a characteristic of many parrotfish species. Juveniles typically display a duller coloration, while adults can exhibit a range of colors from greens and blues to pinks and yellows, often with intricate patterns.
Parrotfish are named for their beak-like teeth, which are used to scrape algae and dead coral off of hard surfaces. This feeding behavior is crucial for the health of coral reefs, as it helps to prevent algal overgrowth and promotes coral growth by keeping the reef surfaces clean for coral larvae to settle.

Care
Bullethead Parrotfish require large, well-established aquariums with plenty of live rock to graze on and space to swim. They are not suitable for small or nano tanks due to their size and activity level. These fish are known to be robust and can adapt to a variety of tank conditions, but they do best in environments that closely mimic their natural reef habitats.
It's important to note that parrotfish produce a significant amount of waste, so efficient filtration and regular water changes are essential to maintain water quality. Additionally, they are known to nibble on stony and soft corals, so they may not be the best choice for a reef tank with a focus on coral diversity.
Reproduction
In the wild, Chlorurus sordidus exhibits complex social and reproductive behaviors, including haremic structures where a dominant male controls a group of females. They are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life, usually when they reach a certain size or in the absence of a dominant male.
Breeding Bullethead Parrotfish in captivity is challenging and rarely achieved by hobbyists due to their complex life cycle and social dynamics.
Habitat
Bullethead Parrotfish are found in a variety of reef environments, from shallow lagoons to deeper outer reefs. They are widely distributed across the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean. They play a vital role in their ecosystems and are often seen actively grazing throughout the day.
