Overview
What to know before you buy.
A North American minnow that turns pink, blue and gold in spawning condition. Wants cool, hard, well-oxygenated water with strong flow — a subtropical fish, not a tropical one.
Care guide
Keeping Rainbow Shiner healthy in a South African setup.
Tank setup
A minimum 100L aquarium suits Rainbow Shiner. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 7–8 and 15–22°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore — flake, frozen, live. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful, active shoaler. Watch it at feeding time and at lights-out to see its real temperament in your tank.
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 Rainbow Shiner 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.
