Natural habitat

The Blue King Tetra is native to the Amazon River Basin, a habitat characterized by densely vegetated areas with slow-moving waters rich in tannins and organic matter. The presence of leaf litter and dark substrates enhances the visibility of the species' vibrant blue coloration.

Where they are found

The species is primarily found in the Rio Madeira basin in Brazil, where the environment is characterized by slow currents and lush vegetation that has a significant impact on their habitat preference.

Aquarium care

In a suitable aquarium, emperor tetras thrive with regular water changes and a well-maintained filter. A dense vegetation setup is not necessary, but some cover will enhance their comfort.

Feeding

Blue King Tetras are not picky eaters and will accept a variety of foods, including high-quality flake foods, live or frozen foods like brine shrimp and daphnia. Their coloration improves significantly with a diet rich in live foods.

Compatibility

Emperor tetras are peaceful and can be housed with various community fish, provided they are not overly aggressive. They do well in groups, ideally kept in schools of six or more.

Breeding

Breeding Kerri Tetras at home involves keeping both males and females in a well-planted tank where they can feel secure. During breeding, males may become territorial and may engage in mild sparring. Eggs are usually laid on plants or near the substrate and require careful attention post-spawning.
