Grayling also belong to the trout family. The body is stretched out and somewhat flattened laterally, which sometimes gives this fish a high-backed form. The head to the mouth is cone-shaped. The small mouth has an under bite. The back fin is like a flag and is conspicuously high and multi-coloured.
Their habitat is cool, fast flowing water, occasionally they are also found in Alpine lakes. This species lives mostly in free water and needs no shelter. As a diet they consume larvae, various insects and also other small creatures.
