Heterandria Formosa – Least Killifish (1 Pair)
The Least Killifish (Heterandria formosa) is one of the smallest livebearers in the aquarium hobby, making them an excellent choice for nano tanks and planted aquascapes. Despite their tiny size, these fish are hardy, peaceful, and active, thriving in groups and community setups with other small, non-aggressive species.
At Aquamas Pets, our UK-bred Least Killifish are healthy, disease-free, and raised in home aquariums with care. They feed well on crushed flake, baby brine shrimp, and other small live or frozen foods. Their small size and gentle nature make them perfect for aquarists looking to add rare and fascinating behaviour to their aquarium.
