Red-Tailed Black Shark, also known as the Red-Tailed Black Dragon Fish or simply the Red-Tailed Shark, is a freshwater fish native to Southeast Asia. It belongs to the family Cyprinidae and is scientifically named Epalzeorhynchos bicolor. This species is highly valued in the aquarium trade for its unique appearance and peaceful temperament.

The Red-Tailed Black Shark has an elongated body with a pointed snout and large, black eyes. Its most distinguishing feature is its red tail, which gives it its common name. The rest of its body is dark grey or black, with silver highlights on the scales along its sides. The fins are typically transparent or slightly translucent, with the exception of the caudal (tail) fin, which is bright red.

This species can grow up to 12 inches (30 cm) in length, making it a medium-sized fish that requires a spacious tank for proper care. A minimum tank size of 55 gallons (208 liters) is recommended for one adult Red-Tailed Black Shark, with additional space required for each additional specimen. These fish prefer slow-moving water with a sandy substrate and plenty of hiding places, such as driftwood and plants.

In terms of diet, the Red-Tailed Black Shark is an omnivore that consumes both plant and animal matter. In captivity, they should be fed a balanced diet consisting of high-quality flake food, pellets, and frozen or live foods like bloodworms, daphnia, and brine shrimp. Feeding them once or twice daily is generally sufficient, but it's important not to overfeed to prevent health issues related to poor water quality.

Despite their intimidating appearance, Red-Tailed Black Sharks are relatively peaceful and do well when kept with other calm community fish. They tend to be more active at night, so providing some low light during the day can help them feel more comfortable. However, they may become aggressive towards smaller or slower-swimming fish if kept in too small of a tank.

Overall, the Red-Tailed Black Shark is a fascinating and beautiful addition to any aquarist's collection. With proper care and attention, these fish can thrive and bring years of enjoyment to their owners.
