Rosy Tetra (Hyphessobrycon rosaceus)

Rosy Tetra Tropical Fish Learn all about the Rosy Tetra's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Rosy Tetra is the right fish for your aquarium.

The Rosy tetra is one of the most beautiful in its group and is a great little fish for communities. There are several variations in colour with differing grades of red body colour and slight differences in black markings on the fins, depending on the origin of the stock for sale. Rosy tetras are undemanding and will acclimate to a variety of conditions although very hard water may prevent the fish from reaching its best colouring. As with many other small tetras, planted aquariums with subdued areas, or darker substrates, will provide the best home, and result in stronger colours and improved health. Whilst peaceful, Rosy tetras may nip at very long finned fish like guppys or siamese fighting fish, especially if the tetras are kept in small numbers.
