It can be done in different ways, and it is always important that there are more males than females so that fertilization is safer.

When spring is approaching, which is when they usually start to reproduce, it is convenient that weeks before you lower the temperature enough so that little by little, you raise it until the ideal moment arrives.

It is also important that the aquarium is free of decoration or even gravel or plants to make it easier and cleaner. To improve the adherence of the eggs to the bottom, you can try putting some mesh scourers so that they do not move.

Fertilization and hatching of the fry

In courtship, the male will constantly chase the female, encouraging her to lay her eggs on the floor of the fish tank, when this happens, which is usually when the male dawns, he sprinkles the more than 5000 eggs with his sperm.

A great fish tank for Shubunkin Goldfish

Shubunkin Goldfish are animals that like to be in motion for as long as possible, feeling uncomfortable when they are in a tank of fewer than 100 litres. For this reason, if you are thinking of getting some of these fish, you have to always opt for one of 100 or much larger, since over time they can reach more than 15 centimetres, taking away space from other species that you have in the aquarium.

Apart from this quality that the fish tank must-have, they resist very well all temperatures, including those around 10 degrees or even less, but as long as it does not exceed a maximum of 25 degrees. In the same way, they can withstand the extreme pH of water, although it is convenient as long as it is around 6.5 to 7.5.

Although these fish can live with a fairly clean pond, it is preferable that the water change is done regularly since in this way we will prevent them from getting sick and have greater durability.

Water care

It is important to put a good filter so that they can have optimal oxygenation, they do not need a high-quality filter like other fish, but if you want them to be well, we recommend that you make a bet for a good filtration system as well as a system of competent oxygenation since it will improve the quality of the water, avoiding the nitrites generated by the marine plants.

The water changes should not be radical, that is, do not change all of the water since they can get sick because they are not used to the change, so it is recommended that it be done partially every week.

The decoration should be sparse since in this way they will be able to move more freely and enjoy the space more. When putting live plants, always remember to hold them very well to the base, as they are very voracious and can rip them off the ground. If you want to try different types of plants, try duckweed or foxtail.
