Description
X-ray Pristella Tetra – Pristella maxillaris
Introduction:
The X-ray Pristella Tetra (Pristella maxillaris) is a unique variation of the standard Pristella Tetra, prized for its semi-transparent body that gives it an “X-ray” appearance. This fascinating fish is small, growing up to 1.5 to 2 inches (4 to 5 cm) in length, and features a delicate, shimmering appearance with visible internal structures. Known for its peaceful nature and striking look, it is a popular choice for community tanks.
1. Natural Habitat and Behavior
- Natural Habitat: The X-ray Pristella Tetra is native to the warm, slow-moving waters of South America, particularly in the regions of Brazil, Colombia, and Venezuela. It is commonly found in areas with dense plant life and shaded conditions.
- Behavior: As a schooling fish, the X-ray Pristella Tetra thrives in groups, exhibiting calm and peaceful behavior. It is very social, often found swimming in tight-knit schools, and does best when kept in groups of at least 6 individuals. It is non-territorial and can be housed with other small, peaceful species in a community aquarium.
2. Aquarium Setup
- Tank Size: A 10-gallon (38 liters) tank is suitable for a small group of X-ray Pristella Tetras. A larger tank will allow for better schooling behavior and provide space for other peaceful fish.
- Substrate: A fine gravel or sand substrate is ideal, as it helps mimic the soft, natural riverbeds of their native environment.
- Decor: Use plenty of plants, such as Java Fern or Amazon Sword, to provide hiding places and shade. Floating plants can also create dim lighting, which is preferred by this species. Driftwood or rocks can also add to the natural look of the aquarium.
- Water Conditions: The X-ray Pristella Tetra prefers slightly acidic to neutral water with a pH range of 6.0 to 7.5, and a temperature between 72°F to 80°F (22°C to 27°C). They thrive in stable water conditions, so it is essential to use a good filtration system and perform regular water changes.
- Lighting: Moderate lighting is best to bring out their translucent appearance without stressing them. Avoid bright, harsh lights that could cause discomfort.
3. Diet and Feeding
- Diet: X-ray Pristella Tetras are omnivores and will happily eat a variety of foods. Their diet should include high-quality flakes, pellets, and live or frozen foods like brine shrimp, bloodworms, and daphnia. They will also nibble on plant matter and algae.
- Feeding Schedule: Feed your X-ray Pristella Tetras once or twice a day, giving them small amounts of food that they can consume in a few minutes to avoid overfeeding and water quality issues.
4. Compatibility with Other Fish
- Compatible Species: X-ray Pristella Tetras are peaceful and do well in community tanks with other non-aggressive species. Compatible tankmates include other small tetras, rasboras, peaceful cichlids, Corydoras catfish, and other similarly-sized fish.
- Incompatible Species: Avoid keeping them with aggressive or large predatory fish that may stress or prey on them. Species like large cichlids or barbs can be too aggressive for the delicate Pristella Tetra.
5. Common Challenges and Tips
- Schooling: These fish are happiest when kept in groups of 6 or more. Keeping them in small numbers may lead to stress and a reduction in their natural behavior. A larger school will make them feel more secure and active.
- Water Quality: Pristella Tetras are sensitive to poor water quality, so regular water changes are essential. Ensure that ammonia and nitrite levels are kept to a minimum and that the tank is well-filtered.
- Shyness: If housed with larger, more aggressive fish, the X-ray Pristella Tetra may become shy and stressed. They do best in peaceful, harmonious tank environments.
Conclusion:
The X-ray Pristella Tetra (Pristella maxillaris) is a captivating species with a translucent body that gives it an “X-ray” look. Ideal for peaceful community tanks, it thrives in schools and adds both movement and beauty to any aquarium. With proper care, this fish will flourish, providing a stunning display of its unique characteristics.
