Yellow Tetra

Though most specimens of this species are a dull, silvery gray in color, some fish develop a metalic gold coloration. In their natural habitat, these fish are prone to contracting a particular type of parasite which causes a reaction resulting in the yellow or gold coloration for which these fish are named. Yellow Tetras are native to the coastal regions of Brazil in South America. These fish can typically be found in lakes and streams but they also tend to inhabit floodplain tributaries and other areas under forest cover.

Tank Set-up

Yellow Tetras are not particularly popular in the aquarium trade, but they tend to do well in a variety of tank environments. These fish can be kept in biotype setups with sand substrate and driftwood branches as well as in traditional planted setups with dim lighting. This species of Tetra can be kept in the community tank, though it may intimidate slow-moving species like Gouramis with their boisterous nature.


In the wild, these Tetras feed primarily on small invertebrates like insects and insect larvae. In the home aquarium, however, they are likely to accept a variety of foods. Offer Yellow Tetras a staple diet of high-quality flakes or granules supplemented with small live and frozen foods such as bloodworms, brine shrimp and Daphnia. To ensure the best health and coloration of this species feed a varied diet on a regular basis.


Yellow Tetras are easy to breed in the home aquarium when conditioned on plenty of live foods. In order to raise the largest number of fry, these fish should be spawned in a separate breeding tank and the parents should be removed following spawning. The breeding tank should be kept at a temperature around 75 degrees Fahrenheit with a pH between 6.0 and 7.0. After spawning, the eggs should hatch 24 to 36 hours later. It is wise to remove the adult fish from the tank after spawning so they do not eat the eggs or young fry.
