Origin[edit | edit source]

South America: Negro and upper Orinoco River basins.

Sexing[edit | edit source]

Only identifiable during spawning when eggs can be seen in the females body. Very difficult to breed in captivity, most specimens found will be wild caught.

Tank compatibility[edit | edit source]

Top dweller, a peaceful community fish to be kept with mid-bottom dwellers who keep out their way. Must be kept in groups of 6 or more.

Diet[edit | edit source]

Primarily carnivorous, liking live/frozen food such as bloodworm and daphnia.

Feeding regime[edit | edit source]

Feed once or twice a day. Will prefer floating foods.

Environment specifics[edit | edit source]

Must have a tight fitting lid on their tank as they're excellent jumpers.

Behaviour[edit | edit source]

Top dwelling shoaling fish. This fish has the ability to leap out of the water and almost "fly" for up to 152.4cm (60")! So extra emphasis on the tight fitting lid for this species!

Identification[edit | edit source]

A very distinctive looking fish. A convex body with "wing" like pectoral fins. The body colour is iridescent silver with small black blotches, the body is almost transparent.
