The Pigmy Sweeper, Dlass Fish, Red Sea Dwarf Sweeper, scientifically known as Parapriacanthus guentheri, is a small, fascinating fish species found in the Red Sea. This species stands out for its unique appearance and ecological role within its marine habitat.
Description & Characteristics
Parapriacanthus guentheri, commonly known as the Pigmy Sweeper, Dlass Fish, or Red Sea Dwarf Sweeper, is a small fish species reaching a maximum size of 5.6 cm. It’s characterized by its elongated body and a slightly compressed profile. The fish has a silver-grey body adorned with black spots and a distinctive dark stripe running along its lateral line.

Habitat and Occurrence
The Pigmy Sweeper, Dlass Fish, Red Sea Dwarf Sweeper, or Parapriacanthus guentheri, is endemic to the Red Sea, where it thrives in a variety of habitats. It is typically found in shallow reef environments, often seeking shelter among coral formations and rocky outcrops. This fish is a common sight at depths ranging from a few meters to around 50 meters, highlighting its adaptability to different depths. Parapriacanthus guentheri is often found in the neritic zone, which encompasses the coastal areas of the Red Sea. This zone is typically defined as extending from the shoreline to the edge of the continental shelf, where light penetration allows for photosynthesis to occur.
Taxonomy
The species Parapriacanthus guentheri belongs to the Class: Teleostei, Order: Acropomatiformes, and Family: Pempheridae. This classification reflects its evolutionary lineage and shared characteristics with other fish species within these taxonomic groups. The Teleostei class represents a vast group of bony fish, characterized by their advanced skeletal structures and adaptations for aquatic life. The Acropomatiformes order encompasses a smaller group of fish, often exhibiting similar morphological features and ecological roles. Finally, the Pempheridae family includes fish that share common traits, including their nocturnal habits, flattened body shapes, and specific feeding strategies.
