Gender differences
The male dwarf sturgeon is slimmer than the female and has a relatively short beard (1–2 mm) that protrudes vertically from the head. You can see this very nicely in the photo.
Multiplication
The female lays around 40 eggs . The male fans fresh water on the eggs until the young hatch, this happens after 6–7 days. The male supports the young when they hatch. The young animals then still have a yolk sac from which they live. They only start to eat after 4–5 days.
