Types of Killifish Species

Our Killifish Collection features a variety of freshwater killifish species known for their bright colors and unique patterns. Each killifish type spends at least 14 days under expert care before shipping to ensure peak health. Freshwater killifish species are normally best kept as male/female pairs or trios or with males separated when not breeding. Killifish males can be aggressive toward females though there are exceptions, so please check the listing for the specific killifish type you’re interested in. We pack every fish in breather bags tucked inside recycled-plastic insulation and ship overnight via UPS to keep stress low. Backed by our 100% live arrival guarantee and friendly support before, during, and after your order, you can shop our killifish species with confidence.
