The Threadfin Rainbowfish Iriatherina werneri is a subtle beauty in both its color and exquisite form. The elegant beauty of these fish may be rather hard to believe when you consider the size of this fish, being only about 2 inches (5 cm) long. It's probably even harder to believe if you have seen the stressed pet store appearance of this fish. But a well bred, healthy, adult Featherfin Rainbowfish will display many different intense colors and beautiful fins.

A school of Threadfin Rainbowfish in breeding condition is easily one of the most spectacular sights in the aquarium. The common names, Threadfin and Featherfin, reflect the elegant fins of mature males. The fins are long and flowing with lovely extended filaments on the dorsal fins.

The gorgeous coloring of the Featherfin Rainbowfish paired with a gregarious and peaceful nature makes them an excellent inhabitant for the aquarium. These fish are fairly adaptable and will live happily in a tank without aggression. They are best suited to a planted tank. This fish dislikes harsh lighting and excessive open water. They do need frequent water changes, but a school of these fish will certainly brighten up any aquarium.

The Threadfin Rainbowfish are best kept by a hobbyist with some rainbow fish experience. They are very sensitive to water condition changes. They are also slow and picky feeders because of their small throats. When they are kept in a community tank extra time needs to be taken to make sure they are getting enough food.
