I have many fertile SRT males and females, and it is not as easy as you would think. The fish have to like each other to pair, then they need to still like each other after they’ve spawned. I’ve had pairs turn on each other after a spawn and have had to start all over. The fish also need time to settle into the tank. Anyhow, it is fun and rewarding, but you’ll go through many fish to find the right matches. At least I did.
