Albino Silver Arowana – Osteoglossum bicirrhosum: A Comprehensive Care Guide
Introduction:
The Albino Silver Arowana (Osteoglossum bicirrhosum) is a striking, rare variant of the Silver Arowana, featuring a creamy white body and captivating red or pink eyes. Growing up to 35 inches (90 cm) in captivity, this albino variant shares similar care requirements but offers a unique aesthetic appeal. The Albino Silver Arowana is highly sought after in the aquarium hobby for its rare coloration, making it a prized addition for experienced aquarists.
1. Natural Habitat and Behavior
While the Albino Silver Arowana does not occur naturally, it retains the same instincts and behaviors as its wild-type counterpart from the Amazon Basin. It is a surface-dwelling predator that is known for its powerful leaping ability, often jumping to catch insects and other prey above the water. In an aquarium, it needs ample open swimming space and a secure lid to prevent escape attempts.
2. Aquarium Setup
For an Albino Silver Arowana, a tank size of 250 gallons or more is essential to support its growth and active swimming habits. The ideal water parameters include a pH of 6.5-7.5 and a temperature range of 75-82°F (24-28°C). While substrate is not critical, smooth gravel or sand, paired with driftwood or rocks, can create a natural look without taking up too much swimming space. Strong filtration and regular water changes are necessary for maintaining clean water and stable conditions.
3. Diet and Feeding
This carnivorous species requires a high-protein diet. Ideal foods include live or frozen fish, shrimp, insects, and protein-rich pellets. Be cautious about overfeeding to prevent water quality issues and obesity. Juveniles require more frequent, smaller meals, while adults can be fed larger portions 2-3 times weekly.
4. Compatibility with Other Fish
Albino Silver Arowanas can be kept with other large, non-aggressive species but may prey on smaller fish. Compatible tank mates include large cichlids, datnoids, and sizable catfish. Avoid small fish or overly aggressive species, as they may trigger predatory responses or stress the Arowana.
5. Common Challenges and Tips
- Jumping: The Albino Silver Arowana is an excellent jumper, so a secure, well-fitted lid is essential to prevent injuries or escapes.
- Sensitivity to Light: As an albino, this fish may be more sensitive to intense lighting. Consider using subdued lighting to avoid stressing it.
- Water Quality: Like other Arowanas, this species is sensitive to water quality fluctuations. Use strong filtration and maintain a regular cleaning routine.
Conclusion
The Albino Silver Arowana (Osteoglossum bicirrhosum) is a stunning, rare fish that requires a spacious, well-maintained aquarium. Its unique coloration, combined with its graceful movements and large size, make it an exceptional choice for experienced hobbyists. With attentive care, it can thrive as a standout feature in any large tank.
