Steel Blue Killi Fish Aphyosemion gardneri 3cm

The Steel Blue Killifish is a stunning and underrated gem of the freshwater hobby. Aphyosemion gardneri, native to West Africa (Nigeria and Cameroon), the males display an extraordinary mosaic of electric blue, red, and yellow markings, while females are more subtly coloured. This listing is mostly female, making it ideal for breeders looking to balance a colony or set up a breeding group.
