Identity and search names

Single-species profile for Rasbora trilineata. Preserve the permanent AquaNexus ID and route; retain former scientific combinations and trade names only as searchable aliases. Search names include Scissortail rasbora, Rasbora trilineata, Three-lined rasbora.

Environment and housing

Long open swimming lanes, moderate current and a tight-fitting lid

Feeding and nutrition

Feeding ecology: Omnivore; varied dry, frozen and live foods

Feeding routine: Small appropriate meals based on age and body condition

Breeding and reproduction

Egg scattering and controlled spawning are documented; adults provide no care and eggs or larvae require separation and appropriately small first foods

Breeding plan: Egg scattering and controlled spawning are documented; adults provide no care and eggs or larvae require separation and appropriately small first foods Parental care: No parental care.

Compatibility plan

Medium peaceful fish that can match its pace

Filtration and aeration

Filtration: Use mature biological filtration sized for the adult group and feeding load, with protected intakes and a flow pattern suited to the species.

Aeration: Maintain dependable gas exchange and dissolved oxygen with surface agitation or supplementary aeration while preserving sheltered resting areas.

Maintenance

Test water routinely, remove waste and uneaten food, service filtration without destroying biofilm and review stocking as animals mature.

Adult projected load

Adult projected load includes mature body mass, social-group size, territorial space, oxygen demand, feeding waste and breeding output.

Welfare and risk

Maintain the stated adult space and social structure, verify feeding and intervene early when injury, exclusion, weight loss, abnormal respiration or altered behaviour appears. Juveniles are sold small, but adults need genuine swimming length. A token group in a short aquarium is not adequate.

Main risk: Juveniles are sold small, but adults need genuine swimming length. A token group in a short aquarium is not adequate.

Biosecurity and release

Never release fish, fry, eggs, aquarium water, sediment, plants or live foods into drains, dams or natural waterways. Confirm current Australian import conditions and South Australian possession, trade and movement rules before acquisition or transfer.

Overridable warnings

Warnings may be overridden only after adult size, group structure, filtration, aeration, compatibility and maintenance capacity are recorded.
