Blue Reef Chromis

Another schooling Chromis, this one dialed all the way up to electric blue — a color group of damsels that trades the usual territorial standoffs for safety in numbers, drifting together over the reef instead of claiming individual turf. Milder-tempered than most of the damsel family, it's an easy sell for anyone who wants motion and color without the attitude.

Care level: Easy · Temperament: Semi-aggressive, milder than most damsels · Max size: ~3" · Min tank: 30 gal · Diet: Omnivore, marine flake/pellet
