Natural habitat

Pristella tetras inhabit coastal rivers in South America, where they migrate with seasonal floods. They thrive in environments with a range of water hardness and conditions, showcasing their adaptability.

Where they are found

This species is notably adaptive, occupying both freshwater and brackish environments. They seasonally migrate to marshlands rich in flora for spawning, showcasing their variation in habitat preferences.

Aquarium care

To create an ideal environment for Golden X-Ray Tetras, provide a well-planted tank with open swimming areas. The aquarium should include gentle filtration to mimic their natural habitat, along with a sandy substrate and low lighting to enhance their color.

Feeding

As omnivores, pristella tetras enjoy a balanced diet of commercial flakes and occasional high-protein snacks such as brine shrimp, bloodworms, and insect larvae, with several feedings throughout the day.

Compatibility

Golden X-Ray Tetras are peaceful and do well in community tanks with other similarly-tempered species. While they can coexist with adult shrimps, care should be taken as they may consume shrimp fry if the opportunity arises.

Breeding

Breeding X-Ray Tetras requires a separate tank with vegetation or spawning mops. As they lay eggs during dawn, conditions should be kept slightly acidic and soft. Post-spawning, parents should be removed swiftly to protect the eggs.
