Key traits
Care guide
Keeping Australian Rainbowfish healthy in a South African setup.
Tank setup
Size the aquarium to Australian Rainbowfish's adult size and activity level. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 6.5–8 and 20–28°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful. Keep it in a group for natural behaviour.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Australian Rainbowfish depends on the line and water chemistry; ask your shop about proven pairs.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
