Description
Peacock Gudgeon – Tateurndina ocellicauda
Introduction:
The Peacock Gudgeon (Tateurndina ocellicauda) is a stunningly colorful fish from Papua New Guinea. Known for its vibrant blue, pink, and yellow patterns, it typically reaches a manageable size of 2-3 inches (5-7.5 cm), making it suitable for smaller aquariums. This peaceful and personable fish is perfect for hobbyists who want to add a pop of color to a peaceful community tank.
1. Natural Habitat and Behavior
In the wild, Peacock Gudgeons inhabit slow-moving streams and rivers surrounded by dense vegetation. They are bottom to mid-level swimmers and have a calm and somewhat curious disposition. They are naturally shy, preferring plenty of hiding spaces among rocks, plants, and driftwood where they can feel safe and explore.
2. Aquarium Setup
A 10-gallon tank or larger is sufficient for a small group of Peacock Gudgeons, though a larger tank is recommended for multiple pairs. Peacock Gudgeons thrive with a soft, sandy substrate and dense plant cover to mimic their natural environment. Caves or tube-like structures also provide necessary hiding and breeding spots. Ideal water conditions include a temperature between 72-79°F (22-26°C), a pH of 6.0-7.5, and relatively soft to moderately hard water. Moderate lighting enhances their colors while keeping them comfortable.
3. Diet and Feeding
Peacock Gudgeons are omnivorous and enjoy a diet of both meaty and plant-based foods. They accept high-quality flakes, pellets, and frozen foods such as brine shrimp, bloodworms, and daphnia. Feeding small amounts two to three times a day keeps them healthy and vibrant. Due to their small mouths, opt for fine-sized food options that are easy for them to consume.
4. Compatibility with Other Fish
Peacock Gudgeons are generally peaceful and make excellent community fish. They do well with other small, calm species such as tetras, rasboras, and other non-aggressive fish. Avoid keeping them with larger or overly active fish that may outcompete them for food. They also do well in small groups, but males may show mild territorial behavior if there’s not enough space or cover, especially during breeding.
5. Common Challenges and Tips
- Shy Nature: Peacock Gudgeons can be shy, especially in new tanks. Dense vegetation and hiding spots help them feel secure.
- Water Quality: They are sensitive to poor water quality, so regular water changes are essential.
- Breeding: They are easy to breed in captivity, and the addition of PVC pipes or caves can encourage spawning.
Conclusion
The Peacock Gudgeon (Tateurndina ocellicauda) is a delightful, colorful fish that can thrive in a well-maintained community tank. With its vibrant colors and peaceful nature, it’s a perfect choice for beginner to intermediate aquarists. Proper care and attention to their environment make Peacock Gudgeons an eye-catching and rewarding addition to any aquarium.
