Hyphessobrycon sweglesi, commonly known as the Red Phantom Tetra, is a small, characin fish belonging to the family Characidae. It is highly valued in the aquarium trade for its striking coloration and peaceful demeanor. The species exhibits a compressed, somewhat deep body shape typical of many Hyphessobrycon species. Males are generally more intensely colored and possess elongated dorsal and anal fins, particularly during breeding periods. A distinctive feature is the prominent black humeral spot, often bordered by iridescent scales, and the reddish-orange to golden-red fins, which give it its common name. This species is known for its schooling behavior and is a popular choice for planted community aquariums.

Consigli per l'identificazione
Humeral Spot
Look for the distinct, vertically elongated black spot behind the gill cover. This is a key identifier.
Fin Coloration
Observe the reddish-orange to golden-red fins, especially the dorsal and anal fins. The dorsal fin often has a black and white margin.
Body Shape
Note the compressed, somewhat deep body, typical of many Hyphessobrycon species.
Sexual Dimorphism
Males are generally more colorful and have noticeably longer, more pointed dorsal and anal fins compared to the rounder, shorter fins of females. Females are also typically plumper, especially when gravid.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Typically found in shallow to moderately deep waters, often near the banks.
- Ambiente
- Native to slow-moving tributaries, streams, and flooded forest areas of the Amazon basin. They prefer areas with dense vegetation, submerged roots, leaf litter, and often blackwater conditions (stained by tannins from decaying organic matter). These environments typically have soft, acidic water.
- Areale geografico
- South America, specifically the upper Rio Guaporé basin in Brazil and Bolivia.
Informazioni sull'acquario
- Livello di cura: beginner
- Temperamento: peaceful
- Dieta: omnivore
- Dimensione minima della vasca: 60 liters (15 gallons) for a small school
- Temperatura: 22-28°C (72-82°F)

- Compatibilità: Excellent for community aquariums with other peaceful, similarly sized fish such as other small tetras, rasboras, dwarf cichlids, corydoras, and peaceful Loricariids. Avoid housing with large, aggressive, or fin-nipping species.
- Requisiti speciali: Requires a well-planted aquarium with open swimming spaces. Dim lighting and a dark substrate can enhance their coloration. They thrive in schools of 6 or more individuals, which reduces stress and encourages natural behavior. A gentle water flow is preferred. Peat filtration or botanicals can help maintain slightly acidic, soft water conditions, mimicking their natural habitat.

Fatti chiave
Schooling Behaviorbehavior
Red Phantom Tetras are obligate schooling fish, meaning they thrive and exhibit their most natural behaviors when kept in groups of at least 6-10 individuals. This schooling instinct provides security and enhances their visual appeal.
Sexual Dimorphisminteresting
One of the most striking features of this species is the clear sexual dimorphism, with males displaying significantly longer and more pointed dorsal and anal fins, often with a black and white margin, and more intense coloration, especially during courtship.
Blackwater Preferencebehavior
In their natural habitat, Hyphessobrycon sweglesi often inhabits blackwater environments, characterized by soft, acidic water stained with tannins from decaying organic matter. Replicating these conditions in an aquarium can significantly improve their health and coloration.
Misnomerinteresting
Despite sometimes being called 'Black Phantom Tetra', the true Black Phantom Tetra is Hyphessobrycon megalopterus. H. sweglesi is more accurately referred to as the Red Phantom Tetra or Golden Phantom Tetra due to its distinct reddish fin coloration.

Specie simili
Black Phantom Tetra
Hyphessobrycon megalopterus
While often confused, H. megalopterus has a more pronounced black body coloration, especially in males, and its fins are typically darker, often smoky black, rather than the reddish-orange of H. sweglesi. The humeral spot in H. megalopterus is usually rounder and more intense black, sometimes with a white upper margin, whereas in H. sweglesi it's often vertically elongated and bordered by iridescent scales. The overall body color of H. sweglesi is lighter and more translucent.
Serpae Tetra
Hyphessobrycon eques
Serpae Tetras are generally more robust, have a deeper red body coloration, and their black humeral spot is typically smaller and less distinct than in H. sweglesi. Serpae Tetras also tend to be more nippy, especially if not kept in large schools, whereas Red Phantom Tetras are consistently peaceful.
Rosy Tetra
Hyphessobrycon rosaceus
Rosy Tetras have a more uniform rosy-red body color and typically lack the prominent black humeral spot of H. sweglesi. While they share similar fin coloration, the absence of the distinct black spot is a key differentiator.
