The Blue Gregory is a hardy Caribbean damselfish with striking electric-blue coloring as a juvenile. Gregories are bold, active, and claim a rock or cave as their territory.
Care: Very hardy and reef safe with corals, but territorial and aggressive toward smaller or similar-looking fish, so add it last. Eats algae, pellets, and frozen foods. Max size about 4–5". Minimum tank size: 30 gallons.
