Pygmy Hatchetfish

The pygmy hatchetfish, found in Colombia and Peru, has small, delicate features and indeed is the smallest hatchetfish. These fish are mild-mannered and eat flake food. Fine for all community tanks but will not do well with aggressive species. These are great schooling fish for the upper region of the aquarium and will even tolerate small nano tanks - and large peaceful tanks.

Care Guide
Tank setup: Hatchetfish live at the very surface, so give them floating plants, gentle filtration and a tight-fitting lid, since they are excellent jumpers.
Feeding: Feed a quality floating flake once or twice a day, only as much as they eat in a couple of minutes. They also enjoy small frozen foods like brine shrimp.
Tankmates: Hatchetfish are peaceful and get along with small community fish such as tetras, rasboras, corydoras and dwarf cichlids. Avoid fish that swim at the surface and might bully them.
Good to know: Pygmy hatchetfish are the smallest hatchetfish and stay near the surface, so floating plants give them cover.
