Can you breed goldfish in a tank?
by
Goldfish will mate in a tank. However, to encourage mating, you’ll first need to set up the right tank conditions. To get your goldfish to mate in a tank, the tank water will need to be stable and properly cycled. The tank should also be large enough to comfortably house two adult goldfish.
To replicate this temperature change in your own goldfish breeding setup, first lower the temperature of your tank to between 10°C/50°F and 12°C/54°F. Then, when you want to induce breeding, raise the temperature of the water by 2°C/3°F per day, until it is between 20°C/68°F and 23°C/74°F.
How often do goldfish breed in a tank?
Sometimes if the water temperature stays warm long enough, the fish will spawn more than once. In warmer climates outdoor goldfish might spawn two or three times a season. In aquariums, if the water temperature remains pretty much the same, they may spawn all year long.
