The fish, up close
Hatchet fish are small, freshwater fish known for their unique body shape resembling a hatchet blade. They have a slender, elongated body with a distinctive upward-facing mouth. Their most striking feature is their large, transparent pectoral fins that resemble wings, allowing them to glide gracefully just above the water's surface. Hatchet fish come in various species, each displaying subtle differences in colouration and fin shapes. These peaceful fish are best kept in schools to reduce stress and showcase their natural shoaling behaviour.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Hatchet fish are peaceful and social creatures that thrive in groups of at least six individuals. They prefer to swim near the top of the tank, often staying just below the water's surface. These fish are known for their unique ability to leap out of the water to catch prey or escape predators, so a tightly fitting lid is essential to prevent accidents.
Tank planning
Maintaining a well-planted aquarium with plenty of floating vegetation mimics the hatchet fish's natural habitat and provides them with security and shade. Due to their shy nature, hatchet fish appreciate a calm environment with diffused lighting. Regular water changes and stable water parameters are crucial to their health and well-being.
