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.
While it isn’t as simple as your common guppy, breeding the gold australe killifish is a rewarding experience nonetheless. To breed them, put a pair of them in a 5-10 gallon tank alone. The easiest way to prepare the killifish for spawning is to feed high protein food, such as bloodworms, mysis shrimp, nutri-diet fish eggs, and high quality flake food. Inducing a spawn is as easy as putting a 'spawn mop' (a “mop” made of yarn) into the tank, and waiting patiently. The eggs will be clear when laid, so the darker the color of yarn, the easier it will be to see the eggs.
Now raising the eggs is a matter of discussion for part two of this series. There are a number of different methods, but I will discuss the one that I used successfully, while still addressing the alternatives. In the meantime, sign up for our free RSS feed and newsletter so you don't miss part 2!
