Golden Cardinal Tetra Care Guide

Introduction

The Golden Cardinal Tetra is a captivating and relatively new variation of the popular Cardinal Tetra, known for its vibrant golden hue combined with the traditional deep blue line that runs through its body. This striking fish adds a flash of color and activity to any freshwater aquarium.

Natural Habitat

While traditional Cardinal Tetras are native to the slow-flowing rivers and streams of South America, particularly the Amazon basin, the Golden Cardinal Tetra has been bred for its unique colouration. They thrive in environments similar to their wild relatives, with soft, acidic water and plenty of plant cover.

Aquarium Setup

To replicate their natural environment, an aquarium for Golden Cardinal Tetras should be densely planted with areas of both shade and light, mimicking the undergrowth of their native habitat. They prefer soft, acidic water with a pH between 5.5 and 7.0 and temperatures ranging from 72°F to 80°F (22°C to 27°C). A dark substrate can help to enhance their golden colouration.

Water Parameters

To maintain optimal conditions, keep the water clean and well-filtered, with regular changes of about 25% per week. Peat filtration or driftwood can help maintain the desired pH and release tannins that mimic natural waters.

Diet and Feeding

Golden Cardinal Tetras are omnivorous and will accept a wide range of foods. High-quality flake foods, small pellets, and frozen or live foods such as brine shrimp and daphnia should be part of their diet. Feeding small amounts two to three times a day will keep them in best health without overloading the aquarium’s filtration system.

Behavior and Social Structure

These tetras are peaceful and schooling fish, thriving in groups of six or more. Keeping them in larger groups reduces stress and enhances their natural behaviour and coloration in the aquarium setting.

Compatibility with Other Species

Due to their peaceful nature, Golden Cardinal Tetras can be kept with a variety of other community fish. They do well with other small, peaceful species such as other tetras, rasboras, and dwarf corydoras. Avoid housing them with large or aggressive fish that might see them as prey.

Breeding

Breeding Golden Cardinal Tetras can be a challenge, similar to their traditional counterparts. They spawn in soft, acidic water and require fine-leaved plants or a spawning mop to lay their eggs. The parents do not care for the fry and should be removed from the breeding tank to prevent them from eating the eggs or fry.

Health Considerations

Like many small fish, Golden Cardinal Tetras can be susceptible to common aquatic diseases such as ich and fungal infections. Maintaining clean water, a balanced diet and regular monitoring are crucial for disease prevention and overall health.

Conclusion

The Golden Cardinal Tetra is a stunning addition to any community tank, bringing colour and life to the aquatic environment. With proper care and attention to their specific needs, they can be a joyful and eye-catching part of your aquarium.
