Yellowtail Blue Damsel

Yellowtail Blue Damsels are omnivores that thrive on a varied diet of high-quality marine flakes, small pellets, and frozen foods like brine shrimp and mysis shrimp once daily. Supplement with occasional vegetable matter such as nori sheets or spirulina-based foods to support digestive health and coloration. Feed small portions that can be consumed within 2-3 minutes to maintain water quality.

This damsel is one of the calmer members of the Pomacentridae family, displaying curious and active behavior throughout the mid-water column. While generally peaceful, they can become territorial and aggressive toward other damsels or similarly-sized fish, especially in smaller tanks; they are best kept singly or in very large established systems. They are bold feeders and will readily investigate new tank additions.

Breeding Yellowtail Blue Damsels in captivity is possible but challenging and rarely achieved by hobbyists. Pairs will establish a territory and lay eggs on a flat surface, with the male guarding the clutch aggressively. Success requires a dedicated breeding tank (50+ gallons), stable conditions, and careful monitoring as fry are difficult to rear due to their small size and specialized dietary needs.
