The gold australe killifish is an uncommon but beautiful fish, and is one of the first out-of-the-ordinary fish that I have ever managed to breed. If you’re like me, and you don’t have a ton of time and money to devote to breeding, these are the perfect fish for beginners to try albeit being somewhat difficult to find. Known scientifically as Aphyosemion australe, these fish tolerate most normal freshwater aquarium conditions, being affected only by far out parameters. Not only are they extremely hardy, but they are really easy to breed! In captivity, the Gold Australe Killifish lives for approximately 3 years, making them one of the longest living killifish.
