My body measures between six and 12 cm long. I have a narrow head with barbels around my mouth. My scales are the color of sand interspersed with lots of small black scales down my sides.
I eat tiny prey such as larvae and worms and even organic particles that I extract by filtering them out of the sand.
I breed between April and July. The female lays between 100 and 500 eggs in the sand. The eggs hatch about 10 days later.
I can live up to five years.
Where and when can you find me in the reserve ?
I live on the sandy beds of slow-flowing waterbodies and lakes. I am a very discreet species.
When to spot me
Buried in the sand during the day, I am mainly active at night. I spend winter in the mud of ditches and shallow habitats.
