Strompfades

Strompfades is a genus of marine ray-finned fishes found in the Indo-Pacific region. It is currently represented by three described species and is distinguished by a laterally compressed body and a continuous dorsal fin.

Taxonomy and discovery: The genus was established in the early 2010s to accommodate species formerly placed in related groups. Diagnostic features include a streamlined profile, a smooth preopercle in some species, and distinctive color patterns that vary across the genus.

Morphology: Adults range around 12 to 22 cm in length. The dorsal fin typically has 9–11 soft rays, and the anal fin has 8–10 rays. Scales are predominantly ctenoid, and the lateral line is continuous. Coloration commonly includes silvery bodies with longitudinal stripes or marbling, which can be more pronounced in juveniles.

Distribution and habitat: Strompfades species occur in warm temperate to tropical waters of the Indo-Pacific, from coral reefs to rocky substrates. They are usually found at depths of 5 to 60 meters, where they shelter among vegetation, rubble, and crevices.

Ecology and behavior: Species are omnivorous, feeding on small crustaceans, algae, and soft-bodied zooplankton. They are typically diurnal and may form small foraging groups or loose aggregations, depending on habitat and resource availability.

Reproduction: Spawning occurs in pairs or small groups during favorable seasons; eggs are demersal and adhesive. Larval stages are pelagic before settling onto reef-associated habitats.

Conservation: There is limited population data, and no widespread listings exist for the genus. Local declines have been reported in some regions, largely linked to habitat degradation and overfishing.
