Overview
What to know before you buy.
A yellow-finned blue-eye from New Guinea whose males flare at each other all day without harm. Prefers slightly hard, alkaline water and looks best in a group over dark substrate.
Care guide
Keeping Forktail Rainbowfish healthy in a South African setup.
Tank setup
A minimum 60L aquarium suits Forktail Rainbowfish. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 7–8 and 22–27°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Micropredator — small live and frozen foods. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful; constant male display. 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 Forktail 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.
