This photo shows two fish swimming in a tank with lots of green aquatic plants in the background. The main fish in the photo is large, with a dark black body with a light blue sheen, and small, thick scales. Its dorsal and caudal fins are quite large, with a light orange or red border. The fish's head is slightly blunt, with a wide mouth and small round eyes. Behind it is a smaller fish, with an elongated body, lighter in color, and speckled patterns on its caudal fin.
