Bentosi Tetra Care Guide: Ornate Fins and Subtle Elegance
This bentosi tetra care guide covers the care of Hyphessobrycon bentosi, a beautifully finned tetra that brings refined elegance to planted aquariums. At Gensou Aquascaping, located at 5 Everton Park in Singapore, we value the bentosi tetra for its graceful deportment, ornate finnage, and compatibility with nature-style aquascapes.
Species Overview and Origin
The bentosi tetra, sometimes referred to as the ornate tetra, hails from the lower Amazon basin in Brazil. It belongs to the rosy tetra clade within the Hyphessobrycon genus, a group known for their deep bodies and elaborate dorsal and anal fins. Males develop particularly impressive fin extensions as they mature, with white-tipped dorsal fins that create a flag-like display. Adults reach approximately 4 to 5 centimetres in body length, with fins adding additional visual impact.
Tank Size and Aquascaping Considerations
A group of eight or more bentosi tetras requires a minimum tank size of 100 litres. They appreciate a well-planted tank with open swimming space in the foreground and midground. Tall stem plants along the back, combined with driftwood and scattered broad-leaved plants, provide the structure these fish enjoy. Their subtle pink-to-salmon body colouration looks particularly striking against a backdrop of lush green plants and a dark substrate. Floating plants that soften the lighting enhance their colour further.
Water Parameters for Bentosi Tetras
Bentosi tetras thrive in soft, slightly acidic water with a pH between 5.5 and 7.0. Temperature should be kept between 24 and 28 degrees Celsius, well within the range easily maintained in Singapore. General hardness of 2 to 12 dGH is ideal. They are sensitive to poor water quality, so efficient filtration and regular water changes of 20 to 30 per cent weekly are essential. Indian almond leaves or peat filtration can be used to naturally soften the water and release beneficial tannins.
Feeding and Nutritional Needs
Bentosi tetras are omnivorous and accept most prepared foods readily. A high-quality flake or micro pellet should form the dietary foundation. Supplement with frozen bloodworms, brine shrimp, daphnia, and live foods when available. A varied diet promotes the best fin development and colour intensity. Feed two to three times daily in small portions, ensuring all food is consumed within a few minutes to prevent waste accumulation.
Fin Development and Sexual Dimorphism
One of the greatest pleasures of keeping bentosi tetras is watching the males develop their ornate finnage over time. Mature males display elongated dorsal and anal fins with vivid white tips, and their body colour intensifies to a warm pinkish hue. Females are slightly rounder-bodied with shorter fins but retain an attractive appearance. Providing excellent water quality and a nutritious diet accelerates fin development and ensures the fish reach their full aesthetic potential.
Temperament and Community Compatibility
Bentosi tetras are peaceful and sociable, making them excellent community fish. They coexist well with other small tetras, rasboras, dwarf cichlids, Corydoras, and small plecos. They are not known to be fin nippers, though males may display to each other with flared fins, which is a natural and harmless behaviour. Avoid keeping them with large or boisterous species that might intimidate them or outcompete them for food.
Breeding Bentosi Tetras
Breeding bentosi tetras is possible in a dedicated breeding tank with very soft, acidic water and dim lighting. They are egg scatterers, depositing eggs among fine-leaved plants or spawning mops. The adults should be removed after spawning, as they will readily consume the eggs. The fry are tiny and require infusoria or liquid fry food initially, progressing to newly hatched brine shrimp after a week. Breeding is not especially difficult but does require attention to water chemistry.
Why Choose Bentosi Tetras
The bentosi tetra offers a combination of beauty, personality, and ease of care that few small fish can match. Its ornate fins and warm colouration elevate any planted tank, and its peaceful nature makes it a reliable community resident. If you would like to add bentosi tetras to your collection or need advice on creating the perfect planted backdrop for these fish, the team at Gensou Aquascaping is here to help with every aspect of your setup.
