The Jewel Damselfish, scientifically known as Chromis chrysura, is a species of damselfish found in the Indo-Pacific region, particularly in the waters surrounding coral reefs. It is also commonly referred to as the Yellowtail Blue Damselfish or Yellowtail Demoiselle.
These damselfish are named for their vibrant coloration and striking appearance. They have a deep blue body with iridescent scales that shimmer in the light, and their namesake yellow tail adds to their beauty. Additionally, they often have a small black spot near the base of their pectoral fin.
Jewel Damselfish are typically found in shallow reef habitats, where they form loose schools or small groups. They feed primarily on zooplankton and small invertebrates, and they play a role in reef ecosystems by consuming algae and helping to keep coral surfaces clean.
In the aquarium hobby, Jewel Damselfish are popular choices due to their attractive appearance, hardiness, and ease of care. They are suitable for reef tanks and community aquariums, but they may become territorial, especially towards other damselfish or similarly colored species. Providing plenty of hiding places and territory boundaries can help minimize aggression.
Overall, the Jewel Damselfish is a beautiful and fascinating species commonly encountered in the vibrant coral reef environments of the Indo-Pacific.
