Black Shark Labeo Crysophekadion 5cm Overview: The Black Shark, scientifically known as Labeo chrysophekadion, is a striking freshwater fish sought after by enthusiasts for its sleek appearance and active behavior. With its dark body and contrasting fins, this fish adds a touch of elegance to any large aquarium. Origin: Originating from Southeast Asia, specifically in rivers and streams of Thailand, Borneo, and Sumatra, these fish thrive in warm, fast-flowing waters. Feeding: These omnivorous fish readily accept a variety of foods, including high-quality pellets, flakes, and live or frozen fare like bloodworms and brine shrimp. A varied diet ensures their optimal health and coloration. Tank Mates: While generally peaceful, Black Sharks can display territorial behavior toward similar-looking or smaller fish. Compatible tank mates include larger, robust species such as barbs, larger tetras, and peaceful cichlids that can handle their active nature. Aggression: Though not excessively aggressive, they may assert dominance in the tank. Providing adequate space and suitable hiding spots can help mitigate potential conflicts. Experience Level: Recommended for intermediate to experienced aquarists due to their need for spacious tanks, understanding of territorial behaviors, and water parameter maintenance. Water Parameters: Black Sharks prefer well-oxygenated water with a pH range of 6.5 to 7.5 and a temperature between 72-79°F (22-26°C). They appreciate clean water conditions, so regular water changes are essential to keep them healthy and vibrant.
