Introduction: Meet the Cardinal Tetra!

The Cardinal Tetra is a small, colorful fish that is native to the South American river basins. They are a popular choice for aquariums due to their bright red and blue colors, making them a standout addition to any tank. They are peaceful fish that thrive in groups, making them perfect for community tanks.

Cardinal Tetra’s Natural Habitat

In their natural habitat, Cardinal Tetras live in the soft, acidic waters of the Amazon river basin. They prefer heavily planted areas with slow-moving water, so replicating this environment in your tank will make them feel right at home. Providing them with plenty of hiding spots and plants will help them feel secure and reduce stress.

Tank Size and Water Parameters

When it comes to tank size, Cardinal Tetras do best in groups of at least 6-8 individuals, and a minimum tank size of 10-15 gallons is recommended. The water should be soft and slightly acidic, with a pH level between 5.0 to 7.0. A temperature range of 72-82°F is ideal for their health and wellbeing.

Diet and Feeding Habits

Cardinal Tetras are omnivores and will eat a variety of foods in the wild, including small insects and crustaceans. In captivity, they can be fed a diet of high-quality flake or pellet food, supplemented with frozen or live foods such as brine shrimp or bloodworms. It’s best to feed them small amounts multiple times a day to prevent overfeeding and maintain optimal health.

Choosing Your Cardinal Tetras

When selecting Cardinal Tetras for your tank, make sure to choose healthy specimens that are active and free of any signs of disease or parasites. Look for bright colors and even fins. It’s best to buy them in groups to prevent any aggression or stress, as they are a schooling fish.

Cardinal Tetra’s Compatibility with Other Fish

Cardinal Tetras are peaceful fish and can be kept with other non-aggressive community fish. Avoid keeping them with larger fish that may see them as a potential snack. They are also sensitive to water parameters, so avoid keeping them with fish that have different water requirements.
