The Cardinal Tetra might be small in size, growing up to only 2 inches (5 cm), but don't let its size fool you. These fish are carnivorous and have a big appetite.

In the wild, Cardinal Tetras feed on a variety of small insects and microorganisms found in the middle and upper water levels of the Amazon. In an aquarium setting, they will thrive on a diet of high-quality flake or pellet food supplemented with live or frozen foods such as bloodworms, daphnia, or brine shrimp.

It's important to note that these fish can be shy when it comes to feeding, so make sure to include plants and hiding spots in the aquarium to help them feel more comfortable and secure.

Born Explorers Naturally Adapted to the Amazon Rainforest

The Cardinal Tetra is found in both blackwater and clearwater streams and rivers in the Amazon rainforest, making them naturally adaptable to different water conditions. In the wild, they are commonly found in slow-moving water and areas with dense vegetation.

These fish are non-migratory and will stay within their home range in the Amazon, making them perfect for a home aquarium. However, it's important to replicate their natural environment when setting up the tank to ensure their well-being.

Cardinal Tetras prefer slightly acidic water with a pH range of 5.0 to 6.5 and a temperature range of 73-81°F (23-27°C). The aquarium should also have plenty of plants and hiding spots to mimic their natural habitat and give them a sense of security.

A Peaceful Fish with a Lively Spirit

One of the reasons why the Cardinal Tetra is so popular among fish enthusiasts is its peaceful nature. These fish are known to be very peaceful and can easily coexist with other peaceful fish of similar size. However, they can also live in a community tank with larger fish, as long as there are enough hiding spots to prevent them from becoming prey.

Despite their peaceful nature, Cardinal Tetras are very active fish and will constantly swim around the tank. They are also known to form schools with their own kind, making them a visually appealing addition to any aquarium.

An Egg-cellent Reproduction Process

When it comes to reproducing, Cardinal Tetras are egg-layers. They will lay their eggs in the thick vegetation of the Amazon rainforest, and the eggs will attach to plant leaves.

During the breeding process, the male Cardinal Tetra will display vibrant colors and chase the female around the tank. Once the female lays her eggs, the male will fertilize them and guard them until they hatch.

Longevity in a Small Package
