Ide­al Tank: Axel­ro­di Rain­bow­fish – Melan­o­tae­nia her­ber­tax­el­ro­di are a very beau­ti­ful, pop­u­lar aquar­i­um fish. A peace­ful com­mu­ni­ty aquar­i­um. Rain­bows would be a per­fect choice in a plant­ed tank. When hous­ing Axel­ro­di Rainbow’s in the home aquar­i­um it is impor­tant to pro­vide them with a longer aquar­i­um that has areas of plants and plen­ty of room as they are active swim­mers. They are also well known jumpers, thus their aquar­i­um should be well cov­ered in order to keep them from jump­ing out of the aquar­i­um if they are star­tled. A dark col­ored grav­el sub­strate may inten­si­fy the Axlero­di Rainbow’s col­or.

Feed­ing: The Axel­ro­di Rain­bow fish should be fed once or twice a day and should con­sume all their food with­in a cou­ple of min­utes. Nev­er leave any uneat­en food in the aquar­i­um. Use a fine mesh aquar­i­um fish net to scoop out any uneat­en food. A flake or pel­let food diet is a good base for the Rain­bow, but should ide­al­ly be sup­ple­ment­ed with live food. Live food ensures the Rain­bow fish is well-nour­ished and health­i­er. Live or frozen brine shrimp is a pop­u­lar Rain­bow fish food since Brine Shrimp is very easy to pro­duce at home. Blood­worms, Micro Worms, Fruit Flies, Mos­qui­to lar­vae, Daph­nia and chopped up Earth­worms are oth­er exam­ples of oth­er suit­able food. Vari­ety in foods is impor­tant for all fish.

Sex­ing: Mature males are larg­er, exhibit­ing brighter col­oration than females. As they grow, mature males will devel­op a much deep­er body with longer dor­sal and anal fins than females do.


Oth­er Con­sid­er­a­tions: Nev­er add these fish to a tank that is not cycled. A well estab­lished tank is best for these beau­ties.
