The 150f stamp depicts the Vittatus Cardinalfish (Apogon victoriae), recognized by its elegant red and white banding. Both species are native to coral reef ecosystems and are prized by aquarists worldwide. This release celebrates the ecological richness of ocean life and Benin’s commitment to environmental themes in philately.
