Ember tetras are relatively small, reaching a maximum length of about 1 inch (2.5 cm) in the wild. In captivity, they tend to grow slightly larger, up to 1.5 inches (3.8 cm) in length. They have a peaceful nature and are easy to care for, making them an excellent choice for community aquariums.

The Importance of Schooling

Ember tetras are schooling fish, which means they thrive in the company of others of their kind. In the wild, they form large schools to protect themselves from predators and to find food more efficiently. In a home aquarium, it’s essential to replicate this schooling behavior by keeping a group of ember tetras together.

Keeping a school of ember tetras can have several benefits, including:
