One of the smallest livebearing fish in the world, the Least Killifish (Heterandria formosa) is a peaceful, fascinating species perfect for natural planted aquariums. Despite the name, these are not true killifish but tiny livebearers that constantly forage among plants, leaf litter, and microfauna.
Their calm temperament and small size make them ideal for nano aquariums and established ecosystems where they can breed naturally and display their unique behaviors.
