Rainbow Shark (Epalzeorhynchos frenatum) - 2" - Live Fish

DESCRIPTION OF ITEM:

The Rainbow Shark (also known as the Red-Finned Shark or Rainbow Red-Finned Shark) is a popular freshwater aquarium fish scientifically known as Epalzeorhynchos frenatum. Despite its name, it is not a true shark but a species of minnow in the Cyprinidae family. This fish is admired for its vibrant colors and active, playful nature.

Key Characteristics of the Rainbow Shark:

1. Appearance:

   • Color: The Rainbow Shark has a distinctive red or orange tail and fins, contrasting with its dark body (usually a shade of gray to black). The vibrant colors are particularly noticeable in mature fish, and the intensity of the color may vary depending on diet, water conditions, and health.
   • Size: Rainbow Sharks typically grow up to 6 inches (15 cm), though some may reach 7 inches (18 cm).
   • Body: They have a streamlined, elongated body with a forked tail, and their dorsal fin is long and pointed, giving them a shark-like appearance.

2. Behavior:

   • Active and Energetic: Rainbow Sharks are active swimmers and prefer to patrol the bottom and mid-levels of the aquarium. They enjoy exploring their environment and are constantly on the move.
   • Territorial: They can be quite territorial, especially if they share the tank with other fish that resemble them or have similar body shapes. Rainbow Sharks may chase or nip at other fish, especially those that enter their perceived territory.
   • Not a true "shark": Despite their name, they are not aggressive toward humans and are not dangerous to other species unless they feel their space is being encroached upon.

3. Diet:

   • Rainbow Sharks are omnivores, meaning they eat a variety of foods, including high-quality fish flakes, pellets, algae wafers, and vegetables (like blanched spinach, peas, or zucchini).
   • They also eat live or frozen foods such as bloodworms, brine shrimp, and daphnia.
   • A well-balanced diet is important for their health, and they should be fed in moderation to avoid water contamination.

4. Tank Requirements:

   • Minimum Tank Size: Rainbow Sharks require a relatively large tank due to their territorial nature. A minimum of 55 gallons (208 liters) is recommended for one fish, with larger tanks being preferred if keeping more than one.
   • Water Conditions:
     • Temperature: They thrive in warm water between 74°F and 80°F (23°C - 27°C).
     • pH: They prefer slightly acidic to neutral water with a pH range of 6.5 to 7.5.
     • Water Quality: It is important to maintain clean, well-filtered water with regular water changes to avoid the buildup of harmful substances like ammonia or nitrates.
   • Substrate: Since Rainbow Sharks are bottom dwellers, they prefer smooth substrate (such as sand or fine gravel) to prevent damage to their barbels.

5. Tank Mates:

   • Due to their territorial nature, Rainbow Sharks are best kept alone or with other species that are large enough or sufficiently peaceful not to provoke them.
   • They can be kept with non-aggressive species like larger cichlids, barbs, and catfish. However, avoid placing them with small or slow-moving fish, or fish with similar body shapes (e.g., other Rainbow Sharks).
   • It’s recommended to keep only one Rainbow Shark per tank to avoid conflicts over territory.

6. Lifespan:

   • Rainbow Sharks typically live for 5 to 8 years in captivity, although some individuals can live longer with proper care.

Summary of Care Tips:

• Provide hiding places: To minimize aggression, offer plenty of caves, plants, and decorative rocks for the Rainbow Shark to establish its territory and have places to retreat when it feels threatened.
• Maintain water quality: Regular water changes and filtration are essential, as Rainbow Sharks are sensitive to poor water quality.
• Monitor tank mates: Choose peaceful, similarly-sized fish to avoid conflict and provide a harmonious environment.

Conclusion:

The Rainbow Shark is a stunning, active, and engaging aquarium fish, known for its colorful appearance and playful nature. However, because of its territorial tendencies, it’s important to ensure that tank conditions are suitable and that it has enough space and hiding spots to avoid stress. With the right care, it can be a wonderful addition to a freshwater aquarium.
