Some species lay their eggs in rivers, which then hatch into the sea, under circumstances entirely different, difficult to reproduce in the aquarium. This is one reason why these fish, come mostly media freedom and, It is one of the reasons why we are launching alarms (on some species) about the risk of entering endangered.
