Black-Winged Hatchetfish

By Gary Bolton

Family: Gasteropelecidae

Species: Carnegiella marthae

Size: 4cm (1 half inch)

Diet: Omnivorous

Tank levels: Upper

Habitat: Forest streams in the Orinoco region

Remarks: The aquarium should be spacious with a secure hood as these fish can leap through the air for some distance, gliding with their wing-like pectoral fins.

Comments: The shape of this hatchetfish is typically very deep with a virtually flat dorsal contour. Light creamy yellow above the lateral line shades down to grey-silver, and a dark outline follows the ventral edge and terminates beneath the eye. The entire body is covered with tiny dark speckles. Pectoral fins are well developed for leaping and gliding above water. This has to be one of the more stranger hatchetfish in the species.
