Triportheus elongatus (Elongate Hatchetfish)

Family: Characidae

Distribution: Triportheus elongatus, commonly known as Elongate Hatchetfish, is a benthopelagic freshwater species that is distributed in the Amazon, Orinoco and Essequibo River basins, as well as parts of Trinidad.

PH: 5.0 – 7.5

Temperature: 22°C – 30C (72 – 86F)

Hardness: 0 – 20

Description: Triportheus elongatus can reach a maximum length of 24 cm.  It has a silver colouration, elongated pectoral fins and a tri-lobed caudal fin.  As you would expect given its name, the Elongate Hatchetfish has an elongated body and a forked tail. 

Diet: Triportheus elongatus will probably accept most foods in an aquarium environment.  You might try feeding it a flake alongside a variety of live and frozen foods.

Breeding: There is not a great deal of information available on this species’ breeding habits.  It appears Triportheus elongatus is yet to be bred in an aquarium environment.

Comments: Triportheus elongatus is a big-sized fish that will need a sizable tank of at least 200 litres, preferably bigger.  You should give it plenty of open swimming space and, if you feel like it, some rocks and plants to simulate its natural environment.  Triportheus elongatus is rarely seen in the aquarium world, which means it is probably better suited to experienced hobbyists.


Recommended Compatible Species: While there is little information available on Triportheus elongatus, it should only be housed with peaceful, similar-sized fish.
