Hyphessobrycon eques, commonly known as the Serpae Tetra, is a small, characin fish native to the Amazon and Guaporé River basins in South America. It is characterized by its vibrant red coloration and a distinctive black, comma-shaped spot behind the gill plate. These fish are popular in the aquarium trade due to their striking appearance and active schooling behavior, though their semi-aggressive tendencies require careful tankmate selection.
Caratteristiche fisiche

- Colorazione
- The body is predominantly a vibrant, deep red to reddish-orange, fading to a lighter shade on the belly. A prominent, vertically elongated, comma-shaped black spot is located just behind the operculum (gill cover). The dorsal fin is typically black with a white tip, while the anal fin is red with a black anterior margin and a white posterior margin. The caudal fin is reddish, and the pectoral and pelvic fins are usually translucent red.

Consigli per l'identificazione
Coloration
Look for the intense red body color, which is a primary identifier. The intensity can vary based on mood, diet, and water conditions.
Black Spot
The most definitive feature is the distinct, vertically elongated, comma-shaped black spot located immediately posterior to the operculum. This spot is usually quite prominent.
Dorsal Fin
Observe the dorsal fin, which is typically black with a clear white tip. This combination is characteristic of H. eques.
Anal Fin
Note the anal fin's coloration: red with a black leading edge and a white trailing edge. This tripartite coloration is a useful diagnostic.
Body Shape
They have a laterally compressed, somewhat deep body shape, typical of many Hyphessobrycon species.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Typically found in shallow, slow-moving waters, often near the banks of rivers, streams, and tributaries.
- Ambiente
- Prefers heavily vegetated areas, including flooded forests, oxbow lakes, and slow-moving sections of rivers. They are often found among submerged roots, leaf litter, and aquatic plants, which provide cover and foraging opportunities. Water is typically soft and acidic, often stained with tannins.
- Areale geografico
- Native to South America, specifically the Amazon River basin (e.g., Guaporé River, Madeira River) and parts of the Paraguay River basin.

Fatti chiave
Schooling Behaviorbehavior
Serpae Tetras are obligate schooling fish and thrive best in groups of 6 or more. Keeping them in smaller numbers can lead to increased aggression and stress.
Fin Nipping Tendenciesbehavior
Despite their small size, Serpae Tetras are known for their fin-nipping behavior, especially towards slow-moving or long-finned tankmates. This is often reduced when kept in large schools, as aggression is typically directed within the group.
Taxonomic Confusioninteresting
Historically, Hyphessobrycon eques has been confused with Hyphessobrycon callistus and Hyphessobrycon serpae. Modern taxonomy generally recognizes H. eques as the valid species for what is commonly sold as Serpae Tetra, with H. callistus often considered a junior synonym or a closely related species from a different locality.
Color Enhancementamazing
The vibrant red coloration of Serpae Tetras can be significantly enhanced by providing a diet rich in carotenoids, such as spirulina, astaxanthin, or color-enhancing flakes, and by maintaining optimal water conditions.
Breeding in Captivitybehavior
Serpae Tetras are egg-scattering spawners and can be bred in captivity, though it requires specific conditions including soft, acidic water, dim lighting, and fine-leaved plants or a spawning mop for egg deposition.

Red Phantom Tetra
Hyphessobrycon sweglesi
H. sweglesi has a more rounded black spot, often with a red halo, and lacks the distinct white tip on the dorsal fin. Its body is generally a deeper, more uniform red, and it tends to be less aggressive.
Rosy Tetra
Hyphessobrycon rosaceus
H. rosaceus typically has a more elongated body, a less intense red coloration, and a black spot that is usually smaller and more circular, often located higher on the flank. The dorsal fin is often black with a white anterior margin, but lacks the distinct white tip of H. eques.
Black Phantom Tetra
Hyphessobrycon megalopterus
While sharing a similar body shape, H. megalopterus is primarily grey to black with a prominent black spot and elongated dorsal and anal fins in males. It lacks the vibrant red coloration of H. eques.
