The most captivating thing about killifish is their different spawning methods, which separate them into three basic groups: annuals, semi-annuals and non-annuals. In the wild, annuals live in temporary pools that dry up each year for periods up to 6 months. They hatch, grow, reproduce and die all in less than a year and their eggs go dormant until the next rainy season.
Semi-annuals inhabit areas that may or may not dry up completely, while non-annuals occupy permanent bodies of water. Keeping killifish ranges from easy to difficult, depending on species. While they do have a few special requirements, if you’re looking for something a little different, killifish are well worth the effort!
