The Skunk Corydoras is a peaceful, enjoyable, active, hardy and armoured catfish that can help keep the bottom of your tank clean. These fish are shoaling species that prefer living amongst other Corys of their own size. This Catfish is popular with hobbyists for community aquariums. The skunk corydoras possess an ability to supply at least part of their oxygen needs by swallowing air at the water's surface. As the air passes through its functional intestinal tract, oxygen is absorbed into the bloodstream.
