Rainbow Tetra

The rainbow tetra is rare in the aquarium trade since it is not commercially bred. When these fish are imported from the jungles of Colombia, they sell quick. The rainbow tetra is a small peaceful schooling fish that adapts well to the fish tank environment. The tetra features long fins and a multi-colored body. These peaceful swimmers should be kept in a school of six or more.

Quick Facts

Care Guide

Tank setup: Give them plants along the back and sides, open swimming space in front and a gentle filter. A dark substrate brings out their color. Keep a lid on the tank, since they can jump.

Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.

Tankmates: They get along with most peaceful community fish of similar size, such as other tetras, rasboras, corydoras, small gouramis and livebearers.

Good to know: Rainbow tetras have red eyes and long, pointed tail fins, and males show the brightest colors.
