Black-Wing Hatchetfish (Carnegiella marthae)

Out of stock

Remarks: Black-Wing Hatchetfish (Carnegiella marthae) come from many parts of the Amazon, Orinoco, and Parana river basins. They get their name from the distinctive body shape - they have a very large, thin curving breastplate that makes the shape of a hatchet. They can be found in clear water as well as tannin-stained creeks. This species remains small, like Marble Hatchetfish (C. strigata) and sports a silver, shining body with a black lateral line and a black trim around the edge of the breast. 

With large, strong pectoral fins, Hatchetfish are capable of launching themselves out of the water. It is recommended that you keep them with a tight-fitting lid. Floating plants are an added measure of protection while also functioning as a calming mechanism. Hatchetfish typically hover high in the water column, with their flat backs parallel to the surface.
