Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

They have a peaceful but highly energetic temperament. They can occasionally outcompete slower fish for food. Their constant movement adds great life to a large display.

Diet

Omnivore

They are omnivorous and generally unfussy eaters. A high-quality flake or pellet should be the daily staple. Provide regular treats of live or frozen bloodworms and daphnia.

Sex ratio

School

They must be kept in a group of at least 6 to 8 individuals. A mixed sex ratio works perfectly fine in a school. Keeping them in large groups reduces stress and enhances coloration.

Feeding frequency

Twice daily

Feed them one to two times daily in small amounts. They are energetic and require regular energy intake. Remove any uneaten food promptly to maintain water conditions.

Bioload

This active species produces a moderate bioload. Clean, well-oxygenated water is absolutely vital for their health. Excellent filtration and regular large water changes are required.

Flow

Stagnant

They originate from fast-flowing streams and require strong water movement. Highly oxygenated water with robust currents is essential. Additional powerheads are highly recommended for this species.

Reproduction

Oviparous

Breeding them in the home aquarium is challenging and rare. They are egg scatterers that require specific water parameter triggers. Commercial breeding often involves hormonal stimulation.

Compatibility & tankmates

They are peaceful, active schooling fish suitable for large communities. They do well with other similarly sized, active species. Avoid keeping them with very timid or slow-moving fish.

Tank level

Middle

They are very active swimmers in the middle and upper levels. They require plenty of open horizontal swimming space. They rarely spend significant time at the bottom.
