Springer's Damselfish

Springer's Damselfish is a small, distinctively marked damselfish restricted to a relatively narrow range in the western Pacific, primarily the Philippines and parts of Indonesia. It belongs to the genus Chrysiptera and is easily recognized by its striking combination of jet-black body color and two bright electric-blue stripes along the upper body. Compared to many of its more widely distributed relatives, it has a more limited geographic distribution, making it a regionally notable species for divers exploring reefs in its core range. It remains a popular subject in the marine aquarium trade owing to its bold coloration.

Identify Springer's Damselfish by:

• Jet-black to very dark grey body coloration
• Two narrow, bright electric-blue stripes running horizontally along the top of the body, one along the upper back and one through the base of the dorsal fin
• Small, deep, laterally compressed body shape, rarely exceeding 6 cm
• Rounded tail and pectoral fins
• Restricted natural range centered on the Philippines and Indonesia The combination of an almost entirely black body with two thin blue stripes, rather than a mostly blue body, distinguishes it clearly from other Chrysiptera damselfish.

Springer's Damselfish is found on shallow coral reefs within a relatively restricted range centered on the Philippines and parts of Indonesia. It typically inhabits reef flats and lagoon environments at depths of 1 to 10 meters, sheltering among coral rubble and branching coral colonies. It favors warm, stable tropical waters generally between 24 and 29°C. Its narrower distribution compared to many related Chrysiptera species makes it more locally concentrated rather than broadly spread across the Indo-Pacific.

Springer's Damselfish are small, territorial reef fish that typically hold a position near a specific patch of coral rubble or branching coral, defending it against similarly sized intruders. They feed on a mix of zooplankton taken from the water column and algae grazed from nearby surfaces, consistent with the omnivorous habits typical of the genus. Social structure generally follows the Chrysiptera pattern of a male maintaining a territory that may overlap with one or more females. Breeding involves courtship displays followed by the female depositing demersal eggs on cleared substrate, which the male guards until hatching. Their restricted range means sightings are concentrated on reefs within the Philippines and neighboring Indonesian waters.
