Colourful

The Congo tetra lives in shoals in rivers with cloudy water. Their shiny bodies make it easier for them to find each other. Because of their beautiful iridescence, they are also called “jewel tetra”.

Eggs sink to the bottom

After mating, the female lays up to 300 dark eggs, which sink to the bottom of the river. The eggs hatch after just one day. The fry are large enough to immediately start hunting for brine.
