The Aphyosemion striatum is a stunning and peaceful killifish species from the dense tropical forests of Central Africa.

At 3–4cm, this species adds both elegance and movement to any planted aquarium or species-dedicated setup.

This fish is perfect for small, soft-water tanks with low light and plenty of plant cover. While relatively hardy, they are best kept by aquarists who can provide a stable, peaceful environment. Aphyosemion striatum are often admired by killifish enthusiasts for their graceful swimming, rich coloration, and ease of breeding.

🧼 Care and Maintenance
