(more) Tracy The beautiful Rosy Tetra is a cheerful active little fish, making it a fun addition to a peaceful community aquarium with other smaller fishes!Rosy tetra Contents The Rosy Tetra, also known as the Rosy Finned Tetra or the Rosey Tetra, has the deep bodied shape of the larger tetras like the Bleeding Heart Tetra. It is relatively hardy, easy to care for, and will get along well with other small peaceful tank mates. A happy fish, it has earned its place in the community aquarium and will reward the hobbyist with hours of entertainment. This little fish is a loose schooling fish and should be kept in a small group. A minimum sized group of 6 tetras is recommended. This group can consist of either its own kind or some of its close relatives such as the Ornate Tetra and the Bleeding Heart Tetra. The Rosy Tetras will not show their beautiful colors unless they are fully content. So be careful that they are not kept with fish that bully them and be sure to provide them with a pleasant environment. They will enjoy an aquarium planted heavily around the edges for shelter, but leaving plenty of room for swimming. Although they prefer softer and acidic water, many tank bred specimens have spent their lives otherwise and will adapt. For more Information on keeping this fish see: |

Habitat: Distribution / Background
The Rosy Tetra, also known as the Rosy Finned Tetra or the Rosey Tetra, was described by Durbin in 1909. They are found in South America, particularly in the Rio Guopore region of Paraguay and in the lower Amazon River Basin of Guyana and Suriname.
- Scientific Name: Hyphessobrycon rosaceus
- Social Grouping: Groups - Best if kept in schools of 6 or more fish.
- IUCN Red List: NE - Not Evaluated or not listed
The Rosy Tetra is a deeper bodied fish with a body shape typical of some of the larger tetras such as the Bleeding Heart Tetra. Its coloration and appearance is very similar to its close relative, the OrnateTetra, with the differences being quite subtle. Both of these fish have a pink to deep salmon body color, though the Ornate Tetra will often appear more transparent. Both species also have darker red markings on their fins. The Ornate Tetra will have a faint grayish 'shoulder patch' which is absent on the Rosy Tetra.
These two tetras can show subtle differences in their fin coloration. The Ornate Tetra will have white markings on their dorsal and pelvic fin extensions, thus the term 'white 'tip'. The Rosy Tetra will have a black marking or 'flag' on its dorsal fin extension, and will sometimes (but not always) have white tips to the fins. But to all rules there are exceptions, and even an occasional Ornate Tetra will have the black 'flag' type marking on its dorsal fin as well.
- Maximum Size: 1.5 inches (3.81 cm)
- Aquarium Hardiness: Moderately hardy
- Aquarist Experience Level: Beginner
Since they are omnivorous the Rosy Tetra should be given a nicely varied diet. They have fairly high vitamin requirements, so quality flake foods should make up about 60-80% of their diet. They love to chase after live foods and may occasionally nibble on plants or algae.
These fish are fairly hardy and a school of six will do best in about a 20 gallon aquarium. The aquarium should be heavily planted around the sides and back and have plenty of open water for swimming in the front. A few hiding places would be appreciated. Woodwork and floating plants will make them feel comfortable.

- Range ph: 6.0-7.5
- Hardness Range: 5 - 19 dGH
- Brackish: No
- Water Movement: Moderate
- Water Region: All - The Rosy Tetra will inhabit all areas of the aquarium, but usually will spend a good deal of their time in the upper or middle or regions.
In a well thought out aquarium the Rosy Tetra will be peaceful, active, and colorful. Be sure to keep them in a group of tetras, six is generally accepted as the minimum number to be housed together. This fish will happily school with its relatives (Rosy Tetra, Black Widow Tetra, White Skirt Tetra, Bleeding Heart Tetra, etc).
Rowdy neighbors will bring out the worst in them, so keep with peaceful and non-fin nipping fish. They will be startled by loud sounds or excessive movement outside the tank, so keep them in a quiet location.
- Venomous: No
- Temperament: Peaceful - This fish requires several of its own kind to school with and should not be subjected to aggressive tankmates.

- Semi-Aggressive (): Threat
- Shrimps, Crabs, Snails: Safe - not aggressive
- Plants: Safe
The males will have longer fins, are more slender and more brightly colored than the females.
Breeding the Rosy Tetra is a tricky, but a healthy pair will usually breed readily when brought together in fairly soft water and a slightly elevated temperature, 80 ° F (26° C). The pair should be isolated, ideally in a separate tank. The pair will distribute eggs on fine leaved plans. The parents should be removed right away. The fry will be free swimming after approximately five days. The tank's water should be changed frequently and care must be taken that no fry are lost in this process. The fry are fairly slow to reach maturity, and ought to be kept isolated until they are too large to be eaten. See a general description of how to breed these fish in Breeding Freshwater Fish and Fish Food for Fry for more information.
- Ease of Breeding: Moderate
Neon Tetra Disease
- The Rosey Tetra will occasionally develop Neon Tetra Disease which is more common in Neon Tetras.
- This has been identified as a microscopic sporozoan in the genus Plistophora.
- It shows up on the fish as a spreading spot or blemish beneath the dorsal fin.
- There have been attempts to cure this disease with the use of Methylene Blue, but it is not always successful, so the disease is considered uncurable.
- This disease has also been spotted on the Glowlight Tetra Hemigrammus erythrozonus, and the Neon Tetra Paracheirodon innesi.
The Rosy Tetra, also known as the Rosy Finned Tetra or the Rosey Tetra, is readily available at fish stores and on the internet. Cost is around $1 - $5 USD per individual.
