What Black Arrow Royal Tetra look like
The Black Arrow Royal Tetra (Inpaichthys sp. 'Black Arrow') exhibits a laterally compressed and fusiform body shape, typically reaching a maximum adult size of approximately 1.5 to 2 inches (3.8 to 5 cm). This species displays pronounced sexual dimorphism, with males showcasing a vivid dark blue-black horizontal band that contrasts sharply against their sleek silver body, while females are generally less colorful and more rounded in shape. Defensive adaptations include a streamlined body that allows for quick evasive maneuvers in the water column, and the presence of a lateral line system that aids in detecting movement and vibrations in their environment. The dorsal fin is elongated and slightly pointed, contributing to their agile swimming capabilities, while the anal fin is also elongated, enhancing their hydrodynamic efficiency. The overall coloration and body structure serve as a camouflage mechanism among aquatic vegetation, providing an additional layer of protection from predators.
Behavior & temperament
The Black Arrow Royal Tetra is a social species that thrives in small to medium-sized schools, exhibiting a hierarchical social structure where dominant individuals may display more vibrant coloration and assertiveness. They predominantly inhabit the mid to upper water column, displaying pelagic tendencies as they actively swim and forage. Breeding behavior is characterized by egg scattering, where females release eggs among aquatic plants, allowing for natural camouflage and protection from predation. Their temperament is generally peaceful, making them suitable for community tanks, although they may exhibit slight territoriality during breeding periods.
Diet & feeding
In the wild, the Black Arrow Royal Tetra is an omnivore, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they require a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to ensure optimal health and coloration.
