Silver Hatchet Fish are distinctive freshwater schooling fish named for their deep, hatchet-shaped body and bright silver colouration. They are surface-dwelling fish that spend most of their time just beneath the waterline, making them an excellent way to utilise the upper level of a community aquarium.
Their unusual body shape and reflective silver scales make them particularly attractive under aquarium lighting. They are peaceful fish and are best kept in groups, where they feel more secure and display more natural schooling behaviour.
Silver Hatchet Fish appreciate floating plants and subdued surface areas, which provide cover and help recreate their natural environment. They are capable jumpers, so a tightly fitting aquarium lid is essential.
They are best suited to peaceful community aquariums with similarly sized fish. Avoid large or aggressive tank mates that may harass or prey on them.

Yes. Hatchetfish are exceptional jumpers, particularly when startled. A secure, tightly fitting lid is essential.
They naturally feed heavily near the surface and appreciate floating foods, small flakes, micro pellets and appropriately sized frozen or live foods.
Yes. They are peaceful and work well with other similarly sized, non-aggressive community fish.
They don't strictly require them, but floating plants provide valuable cover and help the fish feel secure near the surface.
Keeping them without a secure lid
Their ability to jump is one of their defining characteristics. Always use a tight-fitting lid.
Keeping too few fish
They are schooling fish and become more confident in larger groups.
Keeping them with aggressive fish
Large or aggressive tank mates can stress or prey on these relatively delicate surface fish.
Providing too much surface disturbance
Strong surface agitation can make it difficult for them to comfortably occupy their preferred area.
Feeding only sinking foods
They are surface feeders, so include floating or slow-sinking foods that they can easily access.
