The Black Shark (Labeo chrysophekadion), also known as the Red-Finned Shark or Black-Finned Shark, is a large, striking species of freshwater fish that can make an impressive addition to larger aquariums. Native to Southeast Asia, it is characterized by its sleek black body, sharp fins, and bright red or orange fins, giving it a shark-like appearance. Despite its name, the Black Shark is actually a type of minnow rather than a true shark, but its size and appearance can still make it an exciting centrepiece fish in any aquarium. Here’s a care guide for the Black Shark:
Tank Setup:
-
Tank Size: The Black Shark requires a large aquarium, ideally 100 gallons (380 litres) or more, as it can grow up to 14 inches (35 cm) in length.
-
Water Parameters:
-
Temperature: 24-28°C – Black Sharks prefer warm water.
-
pH: Neutral to slightly alkaline (7.0-8.0).
-
Hardness: Moderate (5-15 dGH).
Diet:
- Black Sharks are omnivores, though they tend to lean more towards carnivorous behavior as they grow.
-
Staple Food: High-quality pellets or flakes designed for large fish.
-
Treats: Live or frozen foods such as bloodworms, brine shrimp, and daphnia.
-
Vegetation: Occasionally, supplement their diet with blanched vegetables like zucchini or spinach.
Behavior & Tankmates:
- Black Sharks are generally peaceful but can become territorial, especially as they grow larger. They may not tolerate other large, aggressive fish.
-
Tankmates: They do best with other large, peaceful fish. Good tankmates include other large species like silver dollars, barbs, and peaceful cichlids. Avoid keeping them with smaller fish, as they may become prey, and avoid overly territorial or aggressive fish.
-
Temperament: While peaceful, Black Sharks may become territorial and assertive as they mature. Providing plenty of space and hiding spots will help reduce aggression.
