The crows and kites attack them and take tlIeir bodies over trees, and thus the fish is called as climbing perch, .as the fish might have climbed trees. But the fish cannot climb the tree. Anabas is so much dependent on atmospheric oxygen that it is asphyxiated if kept in water with no access to air. Fish can live out of water for a long period.
