Rainbow shiner is the common name of the fish known by its scientific name as Notropois chrosomus. 'Notropis' means 'keeled back' and 'chrosomus' means 'colored body', so this name describes the rainbow shiner well!

A rainbow shiner prefers the upper and middle levels of the water, but they can also be found swimming and feeding in the lower and middle levels. It gets along well with other tiny, peaceful fish and they are definitely not aggressive. They can be comfortably housed in a community aquarium due to their extra small size and their calm nature. Like most fish, they eat some shrimp, so should not be kept in an aquarium alongside shrimps.

Tiny, calm headwater streams with gravelly and sandy areas and pools are common habitats for this species. Rainbow shiners spawn from the month of April until July and they spawn sometimes over gravelly nests built by other fish species. Males stand out in spawning aggregations for their reddish-purple backs and pectoral fins of neon blue color. The rainbow shiner, like other Notropis, is most likely a drift feeder, feeding on aquatic insects and plant material. Surprisingly, despite its striking presence, this fish is very shy.

The rainbow shiner is a small cyprinid species native to the southeast of the United States.  This species was once native to parts of northern Alabama, but populations have recently spread further. They have been widely distributed all through North America, particularly, Coosa, Cahaba, Alabama, and the Black Warrior River systems in northwestern Georgia, Alabama, and southeastern Tennessee, in the USA.

Did you know...

Rainbow shiner (Notropis chrosomus) fish have increased energy needs during the breeding season for gamete development and sexual reproduction. Therefore, they change their diet to increase their food intake in late winter and early spring before spawning.

In the wild they spawn in the early summer months of May or June, that is when the water temperature is around 60.8-77 F (16-25 C) or when the water temperature starts to rise.

During spawning, male rainbow shiners become territorial and defend their nests.

One great rainbow shiner fact is that they are egg-scatterers. When spawning or breeding, it is best to split the parents into a separate tank since they have a tendency to consume their own eggs.

Their eggs hatch in around a week, depending on the temperature. Fry remain at the bottom after hatching to finish consuming their yolk sac, the fry does not eat anything else during this period. Later, fry will eat vinegar eels, micro worms, and rotifers until they are free to swim. They will then consume newly hatched brine shrimp as they grow larger. When kept in aquariums, they can gradually tolerate larger dry fish foods in granule and flake form.

When you see them in their native habitat range surrounded by plants they will be showing as much color as they can, but once you catch them, their color fades.

Why is it called rainbow shiner?

Thanks to its iridescent vibrant display of colors that happens during spawning or breeding.

Having your own rainbow shiner

Rainbow shiner care can be a little complicated. The recommended tank size is at least 20 gallons and good filtration is necessary. Keep the water temperature at 50-72 F (10-22 C) with a pH level of 6.0 -8.0.

In the wild, this fish feeds on live and small invertebrates, and when in the aquarium, it will eat frozen or pellet flake fish food.

They do not damage plants and need a steady stream of water and plenty of room to swim. Driftwood and water-worn rocks can be used to decorate the tank, along with plants. Sand or small gravel may be used as the substrate.

The Notropis chrosomus (rainbow shiner) is among North America's most colorful fish. The species displays vibrant colors coupled with a peaceful demeanor that can captivate any hobbyist's attention!
