Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

They are peaceful schooling fish but their highly active nature can sometimes be disruptive to very calm species. They are constantly in motion, providing wonderful movement to the tank. They are generally not aggressive towards other tank inhabitants.

Diet

Omnivore

They are opportunistic omnivores that readily accept most aquarium foods. A staple of high-quality floating or slow-sinking pellets is recommended. Supplementing their diet with live or frozen foods like brine shrimp will boost their colors.

Sex ratio

School

A school of at least six individuals with an even mix of sexes is ideal. Males are generally slimmer and display more intense coloration, especially during courtship. Keeping a larger group diffuses any mild aggression between males.

Feeding frequency

Twice daily

Feeding them one to two times daily is usually sufficient for adults. They are vigorous eaters, so ensure food is distributed evenly to the entire school. Only feed what they can consume in three minutes.

Bioload

The Elegant Rasbora produces a moderate bioload due to its larger adult size and active lifestyle. Excellent filtration is necessary to process their waste effectively. Consistent partial water changes are required to keep nitrate levels low.

Flow

Stagnant

They originate from fast-flowing streams and highly appreciate strong water movement. Adding a powerhead or a high-flow canister filter is highly beneficial. This current mimics their natural habitat and encourages proper muscle development.

Reproduction

Oviparous

They are egg-scatterers that deposit their eggs among dense vegetation. The parents will consume the eggs if given the opportunity. Breeding requires a separate, well-planted tank and immediate removal of the adults after spawning.

Compatibility & tankmates

They are robust but peaceful, fitting well in a community of medium to large-sized peaceful fish. Larger barbs, loaches, and medium-sized catfish make excellent tank mates. They may outcompete very small or timid fish for food.

Tank level

Top/Middle

They are powerful swimmers that primarily occupy the middle and upper levels of the water column. They require a spacious aquarium with plenty of open swimming areas. Cover at the surface is appreciated but not strictly required.
