As with most rainbow fish, the male blue eye tenellus rainbow fish have larger fins and more color than the female, but both sexes are attractive. The tenellus is a great example of a small schooling rainbow. In the wild these fish are found in the "billabongs" of Australia (a word for a seasonal pond that only Australians could come up with). We ship these as close as possible to a 50:50 mix of males and females. We recommend a school of six or more, but a pair would do well in a peaceful community tank.

Care Guide
Tank setup: Give them a planted tank with gentle filtration, some floating plants and a lid. They are small, so a sponge over the filter intake keeps them safe.
Feeding: Feed crushed flake or micro pellets once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen brine shrimp.
Tankmates: Blue-eyes are small and gentle, so keep them with other small, peaceful fish such as rasboras, small tetras, pygmy corydoras and shrimp.
Good to know: Male tenellus have long, spotted fins they flare to show off to females.
