These fish originate from Paraguay basin in Southern Brazil.

They have a black and white stripes that run parallel along their body and are a silver grey colour. They have red and yellow eyes. They are placid in nature and best kept in groups of at least four to six with other tetras and small fish as larger fish will bully or prey on them.

They are omnivores enjoying a wide range of foods such as flake food, bloodworms, daphnia and brine shrimp.

They like subdued lighting, dark gravel or substrate, floating plants and bogwood helps darken the water and simulate their natural habitat.

Males are slimmer with females having much deeper bodies.

Breeding is not particularly easy in the home aquarium as they are egg layers and the eggs are photosensitive. Adults will eat their own spawn and fry. They will spawn hundreds of tiny clear eggs early in the morning on fine leaved plants.

The fry should be fed infusoria for around ten days and can later be fed crushed flake food or brine shrimp. They will mature at around a year.
