Rainbow shiner

The rainbow shiner (Hydrophlox chrosomus) is a species of freshwater ray-finned fishes belonging to the family Leuciscidae, the shiners, daces and minnows. This fish is found in North America. The rainbow shiner has a length of 5 to 8 centimetres (2.0 to 3.1 in). It has translucent color from pink to golden with a silver-black stripe along its flanks. The base of its fins are of a reddish color. Adult males change their color during the mating period. Their ventral fins become blue, their head turns purple and their nose turns red. The rainbow shiner was originally endemic to the Mobile River system, where it can be found in small clear rivers of drainage areas of the Alabama, Coosa and Black Warrior rivers in particular. Now it also appears in some rivers in Tennessee and is a popular pet fish for aquariums and ponds. The rainbow shiner spawns between May and June.
