Environment and housing

Open swimming space with dense visual cover and a secure lid

Feeding and nutrition

Feeding ecology: Omnivore; fine dry foods with frozen or live variety

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

Breeding and reproduction

Egg scatterer; adults provide no care and may consume eggs

Breeding plan: Egg scatterer; adults provide no care and may consume eggs Parental care: No parental care.

Compatibility plan

Active short-finned fish; avoid slow, timid or long-finned tankmates

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. Persistent chasing and fin contact are normal risks. Do not use slow, timid or ornamental long-finned tankmates.

Main risk: Persistent chasing and fin contact are normal risks. Do not use slow, timid or ornamental long-finned tankmates.

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.
