I recently lost several fish in my Angelfish Tank, including my Dwarf Green Pike Cichlid, Pimelodus Pictus, and Serpae Tetras (Red Minor Tetras). I have no idea why the Oxygen level in the tank would have been so low, but that sure seems the likely cause of death. • I created this video with the YouTube Video Editor ( / editor )
