Origin[edit | edit source]

South America: Amazon River basin in Peru.

Sexing[edit | edit source]

Very difficult to visually sex, most will only be able to be sexed when the female is holding eggs. Tricky to breed in captivity.

Tank compatibility[edit | edit source]

Peaceful shoaling fish, should be kept in groups of 6 or more. Best kept with mid-bottom dwelling and peaceful tank mates such as Corydoras.

Diet[edit | edit source]

Will accept most floating foods including pellet and flake as well as live/frozen food like brine shrimp.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

A well-filtered mature tank without very bright lighting is needed for this fish. They do not do well in strong currents. A secure lid is a must for this fish, they can get through even the smallest of gaps.

Behaviour[edit | edit source]

Entirely top-dwelling fish, known to jump out the water when startled.

Identification[edit | edit source]

Typical deep-bodied triangular Hatchetfish in shape. The body is silvery and almost translucent with some skeleton visible. It has a black lateral line running along the top of the body to the caudal peduncle. Fins are translucent.
