The rosy tetra (Hyphessobrycon rosaceus) is a small species of characin from the South American countries of Guyana and Suriname.

Like many other tetras, the males have longer dorsal fins than the females.

[citation needed] In the wild, the rosy tetra lives in the Essequibo, Corantijn and Suriname River basins in South America.

[2] The rosy tetra is an egg scattering school spawning fish in the wild.

100 eggs can be laid by one female, usually in the early morning, and over fine leaved plants.
