Care

Springer's Demoiselle is a hardy species that adapts well to life in captivity. It requires an aquarium with plenty of rockwork and hiding spaces to feel secure. This species is omnivorous and will accept a variety of foods, including frozen and flake foods, but a diet that includes live or frozen mysis shrimp and brine shrimp will help maintain its vibrant coloration.

Reproduction

Like many damselfish, the Leptus Damsel is an oviparous species, with females laying eggs that are then fertilized by the male. The male guards the eggs until they hatch. Breeding in captivity is possible but not commonly reported among hobbyists.

Habitat

The Leptus Damsel is native to the Western Pacific, where it is typically found in coral-rich areas of lagoons and outer reefs. It prefers environments with strong water movement and is often observed at depths where light penetration supports healthy coral growth.
