This species of Killifish is named for where it is found in large schools. These fish are endemic to Lake Tanganyika, the second largest freshwater lake in the world by volume and one of the great African Rift Lakes. Tanganyika Killifish are not considered an annual species because the lake in which they live is a body of permanent water. These Killifish are typically silver or gray in color with small spots running laterally along the top half of the body. Some specimens exhibit yellowish coloration along the back and on the dorsal fin as well as on the tops of the caudal fin.
