Welcome to the web site of the American Killifish Association (AKA).  This is your online portal to the fascinating world of killifish.  The killifish hobby is suitable for aquarists of all ages and skill levels, and members of the AKA have always been eager to help all who are interested in killifish. Killifish keepers range from those that have a single nano tank on their desk to those with a basement full of aquaria. You can get into the hobby for only a few dollars, yet with over a thousand killifish species, never get bored.
