Beau Gregory Damsel

The Beau Gregory Damsel (Chrysiptera hemicyanea), also known as the Half Blue Damsel, is a captivating and vibrant species commonly found in the warm waters of the Indo-Pacific region. Its striking appearance and intriguing behaviors make it a popular choice for both beginner and experienced marine aquarium enthusiasts.

Characterized by its distinctive coloration, the Beau Gregory Damsel showcases a deep blue hue on its upper half and a contrasting bright yellow or white color on its lower half. This unique color division is the source of its common name "Half Blue Damsel." Their vibrant colors serve as both a defense mechanism against potential predators and a display of their presence in the marine environment.

These damsels are relatively small, with an average size of about 3 inches (8 cm). Despite their size, they are known for their bold and active behaviors. They often dart in and out of rock crevices and coral formations, adding movement and liveliness to their surroundings.

In marine aquariums, the Beau Gregory Damsel is considered a hardy and adaptable fish, making it a suitable choice for beginners. It can thrive in tanks with appropriate water parameters, including stable temperature, salinity, and water quality. Providing a variety of hiding spots, such as live rock formations, will help replicate their natural habitat and give them places to explore.

While they are generally peaceful, it's important to be cautious when keeping them with other smaller or less aggressive tankmates, as Beau Gregory Damsels can become territorial and display aggression towards fish that encroach on their established space. In larger tanks with ample hiding spots, they are more likely to coexist peacefully.

Offering a balanced diet that includes high-quality marine pellets, flakes, and occasional live or frozen foods will support their health and vibrant coloration. Their active nature and feeding behaviors make them an engaging addition to a well-maintained marine aquarium.

Overall, the Beau Gregory Damsel is admired for its stunning appearance and lively behaviors, making it a charming presence in both natural marine environments and carefully curated home aquariums.
