Sexing[edit | edit source]

Very difficult to visually sex.

Tank compatibility[edit | edit source]

Does appreciate company of it's own kind if the tank is very large with plenty of lateral swimming space, but otherwise a single specimen should be kept as in tight confines they can be feisty towards one another. Can be kept with other similar-sized large robust fish, such as Arowana and Freshwater Stingrays.

Diet[edit | edit source]

Needs a vegetarian diet of blanched vegetables, algae and algae-based pellet or flake food. Will also nibble plants.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

Needs a large spacious tank with plenty of open swimming space, otherwise generally unfussy about decor. Will eat plants and any décor should be secure, prefers a sandy substrate.

Behaviour[edit | edit source]

Generally peaceful but can be territorial if there's not enough space.

Identification[edit | edit source]

A large high-back fish that can be mistaken for the similar Semaprochilodus taeniurus. You can tell the difference by the presence of dark spots on the sides that do not fade as the S.taeniurus matures. Young S. insignis also exhibit these spots but they disappear with age.
