Overview
What to know before you buy.
Gardneri Killifish, or Steel-blue Aphyosemion, are stunningly colored with males displaying a blue body covered in red spots. They are relatively hardy for a killifish but can be aggressive, especially between males. They are known for being excellent jumpers, so a tight-fitting lid is a must.

Care guide
Everything you need to keep Gardneri Killifish healthy in a South African setup.
Water parameters
Keep pH 6–7.5 and 22–26°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Feeding

Behaviour
Gardneri Killifish is generally peaceful. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized peaceful tankmates in freshwater fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Gardneri Killifish vary by line and water chemistry — ask your local shop about proven pairs in SA.
Keeping monster fish?
Big fish are big waste producers — oversized filtration and heavy-duty food carry the tank.
