Instructions
Change part of the water in your feeder goldfish tank once per day to encourage mating. Change out about 20 percent of the water at a time to keep the water quality consistent.
Keep the tank at about 70 degrees Fahrenheit during the day and about 50 degrees at night. Regulate tank temperature with a tank heater and either a small fan placed over the tank or a tank chiller, which you can purchase at a pet or fish supply store.
Feed your goldfish frozen live brine shrimp or worms. A high-quality diet can help encourage mating.
Purchase spawning mops, which are small tassel-like objects, to place in the tank for the female fish to lay eggs on. The surface of the mops is sticky and attractive to female goldfish.
