The Yellowtail Blue Damsel is a vibrant, jewel-toned classic and one of the most popular saltwater fish in the world. Featuring a brilliant, electric blue body that contrasts sharply against a sunny yellow tail, it provides an immediate pop of high-definition color. In the "Answering Machine" era of saltwater husbandry, this species is a top recommendation for those seeking the stunning "blue and gold" look with a significantly more manageable temperament than many other damselfish.
These fish are active, curious, and constantly on the move, making them excellent for bringing life to the mid-levels of the reef. Their small size and extreme hardiness make them ideal for both nano-tanks and large community systems, providing a reliable splash of neon color that remains consistent throughout their lives.

Quick Specs
Care Level: Easy
Temperament: Semi-aggressive
Minimum Tank Size: 20 Gallons
Diet: Omnivore
Reef Compatible: Yes
Max Size: 3 Inches
Water Conditions: 72-78°F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025
Husbandry Notes The Yellowtail Blue Damsel is exceptionally hardy and adaptable, thriving in a variety of aquarium conditions. They are enthusiastic eaters and will readily accept frozen mysis, vitamin-enriched brine shrimp, and high-quality flake or pellet food. While they are far more peaceful than their cousins (like the Blue Devil Damsel), they are still territorial and will defend their favorite hiding spots. Providing plenty of rockwork and caves will help keep them secure and minimize any potential friction with tank mates.
