General: The rosy red tetra naturally occupy tributaries within the southeastern region of the Amazon River Basin. The rosy red tetra will reach a length of two inches and can live for over five years in captivity. Natural behavior can be promoted by incorporating live plants and driftwood into the aquarium.

Dimorphism: The rosy red tetra male will develop an elongated dorsal and anal fin. The female will retain her short fins. Also, the male will display a brighter coloration when ready to reproduce.

Fecundity: The rosy red tetra may produce over 100 eggs per clutch. Eggs will be scattered amongst dense plantings or a spawning mop if one is being utilized. Fry at first will need to be fed infusoria and later on can be switched to live baby brine shrimp once they grow larger.

Aquarium Diet: Rosy red tetras are omnivores and will accept brine shrimp, mysis shrimp, spirulina flakes, daphnia, omnivore pellets, and fish flake.

Water Chemistry: 72-82° F, KH 4-8, pH 5.5-7.5

Compatibility: Rosy red tetras are typically compatible with peaceful species such as the zebra danio (Danio rerio), rasboras such as harlequin rasboras (Trigonostigma heteromorpha) Corydoras species, pencilfish species (Nannostomus sp.), Otocinclus macrospilus, and peaceful tetras such as penguin tetras (Thayeria boehlkei) and pristella tetras (Pristella maxillaris).
