Overview
Hansen's hasemania is an active, peaceful schooling fish that behaves much like the silvertip tetra. It suits a keeper past the beginner stage.
Caring for the Hansen's hasemania
Keep Hansen's hasemania in a group of at least eight to ten. Give the group at least 14 gal (54 L) with open swimming room. Add a sand or fine gravel bottom, driftwood and some hardy planting around the open space.
Keep it in warm water, at 72 to 81°F (22 to 27°C) and a pH of 6.0 to 7.5, soft to moderately hard. Give it steady, gentle flow and clean water from regular changes. Feed quality flake, micro pellets and frozen or live foods such as daphnia, bloodworm and brine shrimp.
A larger group keeps the fish busy with each other and reduces any tendency to nip at tank mates. It suits robust, similar-sized community fish rather than slow or long-finned species. It is an egg-scattering spawner, but settled aquarium breeding of this species is not documented.
Good to know
Hasemania hanseni belongs to the characin family Characidae, and the silvertip tetra is its familiar relative.
In the wild
Hansen's hasemania comes from headwater creeks in the upper Tocantins drainage of Goias, central Brazil.
