General information

The Panamic Sergeant Major, Dermatolepis striolata, is a species of marine fish belonging to the family Pomacentridae, which includes damselfishes and clownfishes. This species is known for its striking coloration and bold stripes, which make it a visually appealing addition to marine aquariums. The Panamic Sergeant Major is also recognized for its resilience and adaptability, traits that are valued by aquarists.

Care

Panamic Sergeant Majors are relatively hardy fish that can adapt to a variety of aquarium conditions. They require a well-established tank with plenty of swimming space and rockwork to provide shelter and territories. These fish are omnivorous and will accept a wide range of foods, including frozen and flake foods, but a varied diet with plenty of marine-based nutrients will promote optimal health and coloration.

Reproduction

In the wild, Panamic Sergeant Majors are known to form breeding aggregations where males prepare and defend nesting sites on the substrate. They are oviparous, with males guarding and aerating the eggs until they hatch. While breeding them in captivity can be challenging, it is possible with careful attention to water quality and providing the right environment for spawning.

Habitat

Native to the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands, Panamic Sergeant Majors inhabit rocky reefs and coastal lagoons. They are typically found at depths ranging from shallow waters to about 30 meters, where they swim in loose aggregations and feed on a variety of food sources, including algae, small invertebrates, and zooplankton.
