What protective behavior do male Clarias batrachus exhibit during the spawning season?

Answer

They build and guard a nest

During the breeding season, the male walking catfish constructs a nest, often using aquatic vegetation, and guards it until the eggs hatch. This form of parental care provides protection to the developing embryos, which increases their survival rates compared to other species that do not guard their eggs.
