1. Natural Habitat and Behavior
- Natural Habitat: Native to South America, particularly in the Amazon Basin of Brazil, the Redtail Penguin Tetra inhabits slow-moving rivers and streams. It prefers environments with ample vegetation and shaded areas.
- Behavior: Known for being peaceful, this species does well in a community aquarium with other non-aggressive species. It is a schooling fish, and it thrives when kept in groups of 6 or more. The Redtail Penguin Tetra is an active swimmer, often seen darting around the tank in a calm, coordinated manner.
2. Aquarium Setup
- Tank Size: A 20-gallon (76 liters) tank is sufficient for a small school of Redtail Penguin Tetras. For larger schools, a larger tank may be necessary.
- Substrate: A soft, sandy substrate works best as it mimics the natural riverbeds of their habitat. Fine gravel can also be used.
- Decor: Redtail Penguin Tetras enjoy densely planted aquariums with floating plants, driftwood, and rocks to provide hiding spots. They appreciate dim lighting and shaded areas that replicate their native environment.
- Water Conditions: The ideal water temperature for these tetras is between 72°F to 80°F (22°C to 27°C) with a pH range of 6.0 to 7.5. Maintaining stable water conditions is crucial to their health.
- Lighting: Moderate to low lighting is recommended to create a calm environment, enhancing their natural colors and encouraging their peaceful behavior.
3. Diet and Feeding
- Diet: Redtail Penguin Tetras are omnivores and will accept a variety of foods, including high-quality flakes, pellets, and live or frozen foods like brine shrimp, daphnia, and bloodworms. They also appreciate occasional plant-based foods, such as spirulina.
- Feeding Schedule: Feed them once or twice a day, offering small amounts of food that they can consume within a few minutes. It’s essential to avoid overfeeding to maintain water quality.
4. Compatibility with Other Fish
- Compatible Species: These tetras are peaceful and work well in community tanks with other non-aggressive fish. They do well with other small tetras, rasboras, Corydoras catfish, peaceful cichlids, and small barbs.
- Incompatible Species: Avoid housing them with larger, aggressive fish, such as certain species of cichlids, as they may stress the Redtail Penguin Tetra or prey on them.
5. Common Challenges and Tips
- Schooling: As a schooling species, the Redtail Penguin Tetra should be kept in groups of 6 or more to prevent stress and to promote natural schooling behavior.
- Water Quality: These tetras are sensitive to poor water conditions, especially ammonia and nitrite levels. Regular water changes and proper filtration are crucial to keeping them healthy.
- Shyness: Although peaceful, Redtail Penguin Tetras can become shy in tanks with overly aggressive tankmates. They will thrive in a calm, peaceful community tank.
