General Description
The Leopold's Tetra (Astyanax Leopoldi) is a species not commonly found in the aquarium trade, belonging to the speciose genus Astyanax within the Characidae family. Native to the Approuague and Oyapock river basins in French Guiana and northwestern Brazil, these tetras reach a maximum size of 6.0cm and are known for their peaceful nature.
Aquarium Setup
Leopold's Tetras require a minimum tank size of 60 litres and are best kept in groups of 8-10 individuals. Their adaptable nature allows them to thrive in various setups, including stream-type environments with gravel substrate, smooth stones, and sufficient water flow. They also do well in Amazon-style tanks or heavily planted tanks, with good oxygenation being crucial for their long-term well-being. Refer to the table for specific water parameters.
Behaviour
These tetras are very peaceful and are suitable for community tanks. They should not be housed with aggressive or significantly larger species. Ideal tankmates include small characins, dwarf cichlids, and peaceful catfish from the Callichthyidae and Loricariidae families. Leopold's Tetras are schooling species by nature and exhibit shoaling behavior, emphasizing the need for a group setting.
Feeding and Diet
In their natural habitat, Leopold's Tetras prey on invertebrates and smaller fish. In captivity, they should be fed a diet rich in small live and frozen foods, supplemented with high-quality dried foods to ensure nutritional balance.
Reproduction & Dimorphism
While there have been reports of successful captive breeding, specific details about the breeding behavior of Leopold's Tetras remain scarce. Sexually mature females tend to be heavier-bodied than males, showcasing slight sexual dimorphism.
Habitat and Distribution
These tetras are commonly found in fast-flowing waters, where they form large shoals in marginal or calmer areas. Their native habitats in the Approuague and Oyapock river basins feature such conditions, allowing Leopold's Tetras to thrive in similar environments.
