American Killifish Association
The World’s Most Brilliant Fish. The Natural Choice for Smaller Aquariums.
Because many killifish are rarely found in commercial pet stores, the AKA connects hobbyists with experienced private breeders, rare species, documented location strains, and the knowledge needed to keep them successfully.

Why Killifish?
Killifish combine extraordinary color, fascinating life cycles, and small-aquarium practicality in a way few freshwater fish can match.
Image unavailableCOLOR
Reef-Quality Coloration
Freshwater fish with vibrant blues, reds, yellows, and intricate patterns that can rival the visual impact of marine reef fish.
Image unavailableLIFE CYCLE
Nature’s Time Travelers
Some annual killifish lay eggs that survive a dry season in damp substrate. Hobbyists can receive resting eggs, add water at the appropriate time, and experience an extraordinary natural life cycle at home.
Image unavailableNANO AQUARIUMS
Built for Smaller Aquariums
Many killifish can thrive in thoughtfully maintained compact aquariums, making them well suited to hobbyists who want remarkable fish without a large setup.
Image unavailableRARE STRAINS
Beyond Big-Box Stores
Many wild-type species and documented location strains are maintained primarily by dedicated hobbyists rather than commercial pet stores.
Image unavailableCONSERVATION
Living Art and Conservation
By maintaining documented populations and sharing them responsibly, hobbyists help preserve genetic lines, collection history, and knowledge that could otherwise disappear.
Image unavailableCOMMUNITY
A Hobby Built on Sharing
Killifish keeping is supported by generations of breeders who exchange fish, eggs, experience, and practical help with other aquarists.

Mission of the American Killifish Association
Read the AKA Mission
The aims of the AKA are to advance the enjoyment, propagation, study and conservation of killifish (oviparous Cyprinodontiform fish) and to promote fellowship amongst its members. The AKA holds an annual convention and killifish show once each year. A number of regional clubs throughout North America are affiliated with the AKA and share its objectives. These clubs meet regularly and hold annual shows. Through these meetings and shows, affiliate clubs provide one of the best ways to acquire killifish and to obtain advice on keeping them. Membership in the AKA is open to everyone within the guidelines of the Constitution and Bylaws.
