How big can a butterfly koi grow in a year? A detailed look at its growth rate

Butterfly koi are ornamental fish whose tail fins look like butterfly wings. Because they are entirely white and very attractive in appearance, they are deeply loved by fish keepers. So how big can a butterfly koi grow in a year?

1. How big can a butterfly koi grow in a year?

How big a butterfly koi can grow in a year depends on the water volume and the feeding method. Generally, a good butterfly koi can grow to 50-100 cm, and some can even grow to 120 cm long. When keeping them, change the water once every two weeks as much as possible, keep the water temperature at 25-30 degrees, and while feeding fish feed, you can also feed some algae and the like to supplement nutrition.

2. How do you keep butterfly koi?

1. Temperature requirements: The most suitable water temperature for butterfly koi is 25-30 degrees, because this fish is prone to catching cold and becoming ill below 21 degrees, and it is also prone to congestion and fin rot.

2. Water quality: The water used for keeping them should be changed at least once every two weeks. When the water is found to be cloudy and not fresh, it should be replaced in time. If the replacement water is tap water, first put the tap water in the sun for 3 days to remove the bleaching powder in it. You can also add an appropriate amount of sea salt to the water to sterilize and disinfect.

3. Feeding: Butterfly koi are not picky about feed. Ordinary fish feed is enough, and supplementing with some algae and the like is also fine. Generally, feed once a day, and the amount fed should not be too much, because fish often eat until they die from overeating. Also, feeding too much food can easily affect water quality.

4. Fish that can be kept together: Butterfly koi can also be kept together with arowanas and stingrays, but note that it is best if the body size is similar to that of the arowana and stingray, or even larger than the arowana.

Overall, it is hard to say how big a butterfly koi can grow in a year, but a good one may grow to around 100 cm.
