Redtail Black Shark (Epalzeorhynchos bicolor) - 1.5" - Live Fish

DESCRIPTION OF ITEM:

The Redtail Black Shark (also known as the Red-Tailed Black Shark or Rainbow Shark with a different coloration) is a striking freshwater fish, scientifically named Epalzeorhynchos bicolor. Despite its name, it's not related to true sharks but is actually a species of minnow from the family Cyprinidae. Its vibrant appearance and territorial behavior make it a popular, albeit challenging, addition to aquariums.

Key Characteristics of the Redtail Black Shark:

1. Appearance:

   • Color: The body of the Redtail Black Shark is typically black or dark brown with a vibrant red-orange tail that contrasts beautifully against its dark body. This distinctive tail is the hallmark of the species.
   • Size: The fish can grow to a length of about 6 to 8 inches (15 to 20 cm), although some individuals may grow slightly larger.
   • Body Shape: The Redtail Black Shark has an elongated, streamlined body, with a sharp, forked tail and a long dorsal fin. The fish’s body is somewhat shark-like, contributing to its name.

2. Behavior:

   • Territorial: One of the key characteristics of the Redtail Black Shark is its territorial behavior. It can be quite aggressive, especially towards other fish that look similar or try to invade its territory. This makes it less suited for community tanks with smaller, more peaceful fish.
   • Active: It is an active swimmer, often patrolling the bottom and middle levels of the tank, and enjoys having space to explore. It can be seen swimming vigorously and occasionally chasing tankmates.
   • Not a true shark: While it resembles a shark in appearance, it does not exhibit the same aggressive tendencies as real sharks. However, it can be aggressive toward other fish, especially similar-looking species.

3. Diet:

   • Omnivorous: The Redtail Black Shark is an omnivore, which means it will eat both plant and animal-based foods. In the wild, it feeds on algae, small invertebrates, and plant matter. In the aquarium, it should be fed a varied diet consisting of:
     • High-quality fish flakes or pellets (both for herbivores and omnivores)
     • Algae wafers to supplement its natural diet
     • Frozen or live foods, such as bloodworms, brine shrimp, and daphnia
     • Vegetables like blanched spinach, peas, or zucchini
   • Algae: In addition to its usual diet, the Redtail Black Shark is known to eat algae, helping to control algae growth in the tank. However, it may not completely eliminate algae from the tank on its own.

4. Tank Requirements:

   • Tank Size: Due to its territorial nature, the Redtail Black Shark needs ample space. A minimum of 55 gallons (208 liters) is recommended for one fish, and larger tanks are preferable if you want to keep multiple fish.
   • Water Conditions:
     • Temperature: The optimal temperature for the Redtail Black Shark is between 72°F and 80°F (22°C - 27°C).
     • pH: A slightly acidic to neutral pH range of 6.5 to 7.5 is ideal.
     • Water Quality: Clean, well-filtered water is essential. Regular water changes are important to maintain good water quality and prevent the buildup of harmful substances like ammonia and nitrates.
   • Substrate: Smooth substrates such as sand or fine gravel are preferred, as sharp, rough substrates can injure the fish’s sensitive barbels.

5. Tankmates:

   • Best kept alone: Redtail Black Sharks are territorial and often don’t coexist well with other species of similar size or body shape. It is usually best to keep them alone or with very peaceful, non-aggressive tankmates.
   • Compatible Tankmates: If you want to keep a Redtail Black Shark with other fish, choose larger species that are less likely to be intimidated or harmed by its aggressive behavior, such as larger cichlids, barbs, and catfish.
   • Avoid other Redtail Black Sharks: Do not keep multiple Redtail Black Sharks in the same tank unless it is very large (over 75 gallons), as they will fight over territory.

6. Lifespan:

   • The Redtail Black Shark has a lifespan of 5 to 8 years in captivity with proper care.

Summary of Care Tips:

• Provide space: Redtail Black Sharks require ample swimming space and are best kept in large tanks with plenty of hiding spots.
• Regular water changes: Ensure water quality is consistently high, with regular filtration and water changes to keep the fish healthy.
• Monitor aggression: Keep an eye on the shark’s behavior and separate it if it becomes overly aggressive with other tankmates.
• Maintain water temperature: Keep the water temperature stable, between 72°F and 80°F (22°C - 27°C), and within the preferred pH range of 6.5 to 7.5.

Conclusion:

The Redtail Black Shark is a stunning and active fish, with its distinctive red tail and aggressive territorial behavior. While it is a great addition to larger tanks with appropriate tankmates, it requires careful attention due to its territorial nature. With the right care, including a large enough tank, good water quality, and suitable tankmates, the Redtail Black Shark can thrive and be a visually striking centerpiece in your aquarium.
