Albino Red-Tailed Black Shark

Epalzeorhynchos bicolor — the Red-Tailed Black Shark — needs little introduction, being one of the most iconic aquarium fish of the past century. The albino form replaces the velvety black body with a pale pearlescent white while keeping the vivid red caudal fin, creating a dramatic contrast that is arguably even more eye-catching than the standard colour. It originates from captive breeding programmes in Southeast Asia.

Care and temperament are identical to the standard form. This is a territorial, bottom-dwelling species that claims and defends a section of the tank against intruders — particularly other members of its own species and similarly shaped fish. Only one specimen per tank is recommended unless the aquarium is very large with multiple distinct territories. Despite its attitude it poses little real danger to mid-water and upper-level tankmates.

The Albino Red-Tailed Black Shark is an omnivore with a strong preference for algae and vegetable matter. It grazes biofilm from surfaces, consumes algae wafers and spirulina pellets eagerly, and also accepts frozen invertebrates and sinking pellets. Regular water changes and stable conditions keep it in excellent colour.

Water: 22–26°C, pH 6.5–7.5, moderate hardness; stable, clean conditions essential. Tank: 150 L minimum; one per tank (unless very large with separated territories); rockwork and caves. Feeding: Omnivore; algae wafers, spirulina pellets, frozen bloodworm; grazes surfaces actively. Breeding: Rarely bred in home aquaria; territorial aggression makes pairing very difficult. Compatibility: Peaceful mid and upper tankmates fine; avoid other bottom-dwelling territorial species.
