Blue Damselfish are captivating small fish, ideal for novice aquarists. The appearance of Blue Damselfish varies by gender; females are entirely electric blue, while males feature orange tails with a vibrant blue body.

These fish grow up to 3 inches and require a minimum tank size of 29 gallons. Blue Damselfish are reef-friendly and do not disturb corals or invertebrates in reef aquariums. They exhibit semi-aggressive behavior, necessitating larger tanks when housing multiple Blue Damselfish to minimize territorial aggression. They may also show aggression towards non-damsel tank mates once settled.

Providing ample live rock is beneficial for Blue Damselfish as it offers hiding spots. When threatened, they retreat into the rockwork and darken in color, returning to their striking blue hue once the threat subsides.

As omnivores, Blue Damselfish thrive on a diet rich in both meaty and plant-based foods. They are enthusiastic eaters, and a diet including mysis and brine shrimp, frozen foods, and high-quality pellets and flakes will ensure their health and vitality.
