Meet the Platinum Slayer, a dazzling and resilient fish perfect for aquariums. Discover its care needs, ideal tank mates, feeding habits, and more here.

The Platinum Slayer, also known as the Platinum Arowana (Osteoglossum bicirrhosum), is a stunning freshwater fish prized for its shimmering scales and majestic presence. Originating from the slow-moving waters of the Amazon Basin, this fish is a true showstopper in the aquarium world. Below is a comprehensive guide to understanding and caring for the Platinum Slayer:

Physical Characteristics:

• Size: The Platinum Slayer can grow up to 36 inches (91 cm) in captivity, making it one of the largest freshwater aquarium fish.
• Coloration: Known for its metallic, platinum-like scales that reflect light beautifully. This distinctive coloration makes it highly sought after by aquarists.

Tank Requirements:

• Tank Size: A minimum of 250 gallons is recommended to accommodate their large size and active swimming behavior.
• Water Parameters: Ideal conditions include a temperature range of 75-86°F (24-30°C), pH between 6.5-7.5, and soft to moderately hard water (3-12 dGH).
• Substrate and Décor: Use fine sand or smooth gravel substrate. Provide ample open swimming space along with sturdy décor like driftwood and large rocks. Ensure any tank decorations are secure, as the Platinum Slayer is a powerful swimmer and may dislodge them.

Behavior and Temperament:

• Platinum Slayers are generally solitary and territorial, especially as they grow larger. They are best kept alone or with very carefully chosen tank mates.
• They are surface dwellers and known for their graceful swimming and occasional jumps, so a tight-fitting tank lid is essential to prevent escapes.

Tank Mates:

• Suitable tank mates include other large, non-aggressive fish such as large catfish, pacu, and other arowanas (with caution).
• Avoid keeping with small fish that can be seen as prey or aggressive species that may provoke stress or fights.

Feeding Habits:

• Platinum Slayers are carnivorous and require a diet rich in protein. Feed them a variety of foods including live or frozen fish, shrimp, insects, and high-quality carnivorous pellets.
• Young Platinum Slayers should be fed twice daily, while adults can be fed once daily or every other day.
• Ensure the food is appropriately sized to prevent choking and encourage natural hunting behavior.

Breeding:

• Breeding Platinum Slayers in captivity is extremely challenging due to their size, specific environmental needs, and territorial nature.
• They are mouthbrooders, with males carrying fertilized eggs in their mouths until they hatch.
• A large, specialized breeding tank with precise water conditions and plenty of hiding spots is required for any successful breeding attempt.

Health and Care:

• Maintain excellent water quality through regular water changes and powerful filtration to support their large bioload.
• Monitor for common health issues such as ich, fin rot, and parasitic infections. Treat promptly with appropriate medications if necessary.
• Provide a varied and balanced diet to ensure they receive all necessary nutrients and maintain optimal health.
