The Ornate Tetra is a graceful schooling fish with a rosy hue and flowing fins. Easy to care for and a perfect addition to any peaceful community tank.
Overview
Hyphessobrycon bentosi is one of the most elegant small tetras in the family Characidae, inhabiting slow-moving tributaries and flooded forests of the Amazon basin in Brazil and Guyana. The Ornate Tetra has long been popular in the aquarium hobby thanks to its refined beauty and undemanding nature.
The fish grows to 4–5 cm and lives 3–5 years with good care. The body is deep and laterally compressed, with a characteristic pinkish-salmon hue that intensifies with maturity. The main attraction is the elongated dorsal and anal fins with white tips, especially prominent in males. Males are larger, more vividly colored, and possess longer fins, making them true showpieces in the aquarium.
Hyphessobrycon bentosi is often confused with close relatives — the Rosy Tetra and the Bleeding Heart Tetra. The Bentosi can be distinguished by its more compact body and the absence of a characteristic red spot on the flank. The behavior rating is 2 out of 5 — a peaceful, calm fish that is perfectly suited for community tanks.
Tank Requirements
A school of Ornate Tetras requires an aquarium of at least 70 liters. Optimal water parameters are: temperature 22–28 °C, pH 6.0–7.5, and general hardness GH 3–10. The species adapts well to various conditions, making it an excellent choice for beginning aquarists.
The tank is best set up in dark tones — it is against a dark substrate and driftwood that the Bentosi's rosy coloration truly shines. Use driftwood, fallen Indian almond leaves, and dense vegetation along the sides and back wall. Leave the central zone open for swimming. Floating plants will create subdued lighting in which the fish feel more comfortable and display richer coloration.
Keep Bentosi Tetras in a school of at least 6–8 individuals. In a group, the fish behave more confidently, males more actively display their fins to one another, and the overall tank picture becomes far more engaging. Water flow should be gentle to moderate.
Feeding and Diet
Hyphessobrycon bentosi is an omnivorous fish with a good appetite. In the wild, the diet consists of small insects, larvae, planktonic crustaceans, and plant detritus. In the aquarium, the staple diet should be high-quality flakes or small pellets for tropical fish.
Regularly supplement with live and frozen foods: small bloodworms, daphnia, brine shrimp, and cyclops. Live food is especially valuable for enhancing coloration — the pink and red tones become noticeably more vivid with a varied diet. A small amount of vegetable supplementation is also beneficial: blanched spinach and spirulina flakes.
Feed 1–2 times daily in small portions consumed within 2–3 minutes. Bentosi Tetras actively take food in the water column and at the surface. Overfeeding should be avoided — small tetras are prone to obesity, especially on a monotonous dry food diet.
Care and Maintenance
The care level for Hyphessobrycon bentosi is rated 2 out of 5 — this is a genuinely undemanding species that forgives beginners their minor mistakes. Nevertheless, stable conditions are essential for health and longevity.
Weekly water changes of 20–25% are mandatory. Standard filtration for a tank of this size is sufficient: an internal or small external filter. Monitor parameters: ammonia and nitrites at zero, nitrates below 25 mg/l.
Ornate Tetras are hardy, but under stress or with a weakened immune system they can be susceptible to common diseases: ich and fungal fin infections. Clean water and a varied diet are the best prevention. If the impressive fins are damaged (which sometimes happens when kept with more boisterous fish), they regrow quickly provided tank conditions are good.
Pay attention to lighting: under overly bright light, Bentosi Tetras fade and seek hiding spots. Subdued or diffused lighting brings out their beauty.
Compatibility
Hyphessobrycon bentosi is an ideal fish for a peaceful community aquarium. It shows no aggression and does not bother tankmates when kept in a sufficient school.
Excellent companions include other peaceful tetras of similar size: Neon Tetras, Black Neon Tetras, Glowlight Tetras, and Emperor Tetras. Close relatives — the Bleeding Heart Tetra and Rosy Tetra — are also perfectly compatible and together create a stunning color palette.
They coexist well with Harlequin Rasboras, Panda Corydoras, Pygmy Corydoras, and dwarf cichlids such as Cockatoo Apistogramma and Bolivian Rams.
Avoid housing with large or aggressive species, as well as active fin nippers that may damage the Bentosi's flowing fins. Tiger Barbs are poor companions for exactly this reason.
Breeding
Breeding Hyphessobrycon bentosi is rated 3 out of 5 in difficulty — an achievable task for an aquarist with basic experience. These are egg-scattering fish with no subsequent parental care.
Prepare a breeding tank of 15–20 liters with soft, slightly acidic water: temperature 26–28 °C, pH 6.0–6.5, GH 3–6. Line the bottom with fine-leaved plants — Java moss, Cabomba — or a spawning grid. Lighting should be minimal: Bentosi eggs are light-sensitive.
For 1–2 weeks before spawning, generously feed the breeders with live foods. Select a pair — a male with the most vivid coloration and long fins, and a female with a noticeably rounded belly. Transfer them to the breeding tank in the evening. Spawning typically occurs in the morning: the fish perform characteristic courtship dances, and the female scatters small, semi-transparent eggs among the plants.
Remove the adults immediately after spawning. The larvae hatch within 24–36 hours and become free-swimming by day 3–4. First food should be infusoria and liquid fry food, transitioning to baby brine shrimp after about a week. Fry grow moderately and begin developing their rosy hue by 2–3 months of age.
