The Rosy Tetra comes from South America, particularly in the Rio Guopore region of Paraguay and in the lower Amazon River Basin of Guyana, Suriname, and Brazil. The species is found in several river systems, including the Rio Essequibo, Rio Corantijn, and Rio Suriname. These tetras prefer the heavily forested, sluggish tributaries off of main rivers. The waters they inhabit are normally stained brown and very acidic. They live in schools in these river systems feeding mostly on small invertebrates.
The Rosy Tetra is a fun addition to a peaceful community aquarium with other smaller fishes. It has the deep-bodied shape of larger tetras, like the Bleeding Heart Tetra. This pretty little tetra has a deep salmon-colored body highlighted with red accents and bright white tips on the fins. Hence, it is also known as the Rosy Tetra.
Multiple companions are needed for this little fish and it will get along well with other small, peaceful tankmates. This loose-schooling fish should be kept in a small group. A minimum-sized school of 6 tetras is recommended. This group can consist of either its own kind or some of its close relatives, such as the White Fin tetra and the Bleeding Heart Tetra. The White Fin Tetra is so similar, in fact, that the Rosy Tetra was at one time considered its subspecies.
