Breeding in May to October

Parents build bubble nests, in shallow freshwater areas amid plants and lay their eggs below. They usually remove all aquatic plants to make a nest 0.4 – 0.6 m2 large to spawn. The eggs float on the surface and stick to each other. Male and female stay around the nest to protect and nurse there young. Until they can search for food and escape from enemies by themselves.
