Aquaristics

Keeping and care

The peaceful animals are popular aquarium fish , mostly in the middle and upper water zone. They do not have any special requirements for water quality and are also relatively easy to breed. However, it must be taken into account that the free spawners are also spawning predators, so the parent animals should therefore be caught after spawning.
