How do goldfish act when spawning?

When goldfish are ready to spawn, their behaviour will change. The males will become more active and chase the females around the tank. They may also display their fins and make grunting noises. The females will become swollen with eggs and their bellies will turn red or pink.

When the female is ready to lay her eggs, she will swim to a plant or other object and lay them in a long string. The male will then swim over and fertilise the eggs. The eggs will hatch within a few days, and the fry will be free-swimming.

Here are some additional signs that goldfish are spawning:

* The fish may become more aggressive towards each other.

* They may lose interest in food.

* They may hide more often.

* The water may become cloudy or milky due to the release of milt (the male's sperm).

If you think your goldfish are spawning, it is important to provide them with a safe environment. Make sure the tank is clean and free of sharp objects. You should also provide plenty of hiding places for the fry.

Spawning is a natural process for goldfish, but it can be stressful for the fish. By providing them with a safe environment, you can help to ensure that the spawning process is successful.
