Jumbo Cardinal Tetra: A Stunning and Peaceful Schooling Fish

The Jumbo Cardinal Tetra (Paracheirodon axelrodi) is a larger and more vivid variation of the classic Cardinal Tetra, known for its striking red and blue stripes that extend the entire length of its body. Unlike Neon Tetras, whose red stripe only partially spans their body, Cardinal Tetras boast full-body brilliance, making them a visually superior choice for aquariums. These peaceful schooling fish are ideal for aquarists seeking vibrant colours and lively activity in their tanks.

Caring for the Jumbo Cardinal Tetra

Jumbo Cardinal Tetras thrive in tanks of at least 60 liters, with soft, slightly acidic water to replicate their Amazonian habitat. They prefer water temperatures between 23°C and 27°C, with a pH range of 5.0–7.0. Use dense planting, driftwood, and dim lighting to enhance their natural colours and provide hiding spaces. Regular water changes and efficient filtration are crucial to maintaining their health and vivid appearance.

Cardinal Tetra vs. Neon Tetra

While Cardinal Tetras and Neon Tetras are often confused, they have distinct differences. The red stripe of Cardinal Tetras spans the entire length of their body, whereas Neon Tetras have a shorter red stripe that ends midway. Additionally, Cardinal Tetras are slightly larger, making them better suited for aquarists looking for a more prominent schooling fish.

Feeding Jumbo Cardinal Tetras

A varied and nutrient-rich diet is essential for maintaining the health and colours of Jumbo Cardinal Tetras. High-quality flakes or micro-pellets serve as a reliable staple. Supplement with live or frozen foods like brine shrimp, bloodworms, and daphnia. Occasional blanched vegetables, such as spinach or zucchini, provide additional nutrition and promote overall vitality.

Compatibility with Angelfish and Other Tank Mates

Jumbo Cardinal Tetras are peaceful schooling fish that thrive in groups of at least six. They pair well with non-aggressive tank mates, including Corydoras, Harlequin Rasboras, and small gouramis. When paired with Angelfish, ensure the Angelfish are not overly large or aggressive, as smaller Cardinals might be seen as prey. Introducing them together at a young age can promote harmony. Avoid housing them with predatory or overly territorial species.

Breeding Jumbo Cardinal Tetras

Breeding Jumbo Cardinal Tetras requires a dedicated tank with soft, acidic water, dim lighting, and fine-leaved plants for egg-laying. Males intensify their colours during courtship to attract females. Once eggs are laid, remove the adults to prevent predation. The fry hatch in 24–36 hours and should be fed infusoria or finely crushed fry food until they grow larger.
