Pygmy Hatchetfish

A tiny, deep-bodied surface fish with the characteristic hatchet-shaped profile. Adults generally stay around 2–2.5 cm and spend much of their time close to the water surface.

Aquarium and care

Keep a group of eight or more in a mature aquarium with gentle circulation, floating cover, and soft, stable tropical freshwater. A close-fitting lid is essential because hatchetfish can jump through small gaps. Leave some surface open for feeding.

Feeding

Offer tiny floating foods and small live or frozen foods positioned near the surface. They may miss food that sinks quickly, so observe feeding rather than assuming they have eaten.

Temperament and tank mates

Choose tiny peaceful companions that will not crowd the surface. Large fish and boisterous feeders are unsuitable.
