How to look after
Gasteropelecus sternicla
Silver hatchet fish
(Linnaeus, 1758)

(Other members of the genus Gasteropelecus)

ADULT SIZE: 5 cm

WATER CONDITIONS: Moderately soft and acidic

TEMPERATURE RANGE: 23-28 C

FOOD: Feed Gasteropelecus sternicla live and dried foods

DISTRIBUTION: This species comes from Guyana, Peru, Surinam, Venezuela

AQUARIUM CARE: Does fine in a planted community tank, with some floating plants. This Amazonian shoaler often jumps out of the water to catch insects in flight. This behaviour also occurs in the aquarium, and so tanks should always have adequate covers to prevent losses. They relish all live foods, both worms etc, but are particularly fond of fruit flies.
Like all shoaling characins, hatchetfish need to be kept in a social group of at least 6 individuals, but preferably more.

Fishkeeping Facts and Tips

The biggest killer of tropical fish is overfeeding. Uneaten food decays and pollutes the water, even with adequate filtration. Adult fish should remain unfed one day each week, and almost all commonly available species will be completely fine if unfed during a two week vacation
