Natural habitat

The Pretty Tetra is typically found in the clear waters of the Amazon River Basin in Peru, where it inhabits small streams and rivers rich in vegetation.

Where they are found

This species predominantly inhabits the Amazon Basin, where it is found in slow-moving waters with abundant vegetation. They are often associated with areas rich in plant life that provide food and shelter.

Aquarium care

In aquariums, the Pretty Tetra should be kept in a school of at least six individuals to ensure they feel secure and display their natural behavior. The tank should be well-planted with open swimming areas and gentle water flow. Regular water changes and maintenance are essential to keep water parameters stable and conducive for their health.

Feeding

Pretty Tetras are omnivores with a diet that includes flake foods, micro pellets, and occasional offerings of frozen or live foods like brine shrimp, daphnia, and bloodworms. A varied diet enriches their nutrition and enhances their colors.

Compatibility

Pretty Tetras are ideal for community tanks due to their peaceful nature. They make excellent companions for other small, non-aggressive fish, provided the aquarium is spacious enough to accommodate their schooling behavior.

Breeding

Breeding requires slightly acidic water and dense vegetation where eggs can be deposited. They are egg layers, and parents should be removed after spawning to prevent them from eating the offspring.
