Hailing from the land down under, Rainbowfish have become hugely popular in the last couple of decades, due to their beautiful colors and peaceful nature. New species are regularly being discovered and offered for sale in the aquarium trade.
Rainbowfish are believed to have evolved from the same evolutionary line as the marine silversides species. In fact, some Rainbowfish still favor a brackish environment, and a few live in a fully marine environment. All species of Rainbowfish have two separate dorsal fins that are narrowly separated. Another distinguishing feature of Rainbowfish is the fact that they lack a lateral line.
Most species of Rainbowfish are schooling fish, a fact that is often overlooked by owners. They also enjoy well planted habitat (preferably live plants) as well as live foods. In their native habitat they are known for keeping the mosquito population under check.
