A slimy fish

The tench is greenish in colour and has small scales. Its body is covered in a thick layer of slime that protects the tench from parasites and bacteria. It was once believed that this slime could cure illnesses, and that other fish would rub up against the tench to heal their own scratches and wounds.

Ecological impact

When there are too many tench in one lake and no predatory fish, there is not enough food for the tench. Their growth begins to slow and they remain small.

Excursion

You have to keep your eyes open to see a tench in nature. It is very shy. The best times to see tench are morning and evening. During the day it hides between the aquatic plants. The tench is a common Danish freshwater fish.

Tiny bubbles

On a warm summer evening you can see tench rolling on the water's surface when they are seeking food in shallow water. When the tench is searching for food on the lake bottom, gas is released into the water. This can be seen in the form of bubbles on the water's surface.
