Scientific Name: Psalidodon anisitsi — formerly Hyphessobrycon anisitsi.

Description: A hardy, active tetra with a shimmering silver body, red-orange fins and a distinctive black marking at the base of its tail. Confident and energetic, these shoaling fish are best suited to spacious aquariums with similarly robust companions.

Origin: South America; the Paraná and Uruguay river systems in Brazil, Paraguay, Argentina and Uruguay.

pH: Approximately 6.0–8.0.

Temperature: Around 18–25°C; avoid prolonged exposure to high tropical temperatures.

Adult Size: Approximately 6–8 cm.

Lifespan: Approximately 5 years, potentially longer with good care.

Food: Omnivorous. Feed quality tropical flakes or small pellets, including vegetable-based foods, supplemented with frozen or live brine shrimp, daphnia and occasional bloodworms. Provide regular plant-based food, as this species naturally consumes vegetation.

Compatibility: Best kept with similarly sized, active fish sharing compatible water requirements. Keep in groups of at least eight, preferably ten or more, to help reduce chasing and fin-nipping. Avoid timid, slow-moving or long-finned fish such as bettas and fancy guppies. Small shrimp may be eaten.

Habitat: Provide an established freshwater aquarium with plenty of open swimming space, driftwood and sheltered areas. This species often eats soft-leaved plants, so use hardy plants with the expectation that some grazing may occur. Maintain effective filtration, good oxygenation and regular partial water changes.
