Koi fish do not recognize their owners. Fish are relatively primitive animals, their brains are not as developed as those of mammals, and most of them do not have the ability to recognize their owners. However, if you feed the koi at a fixed time every day and develop a habit, the koi will actively float its head to eat when it finds the feeder coming to feed. This is a conditioned reflex formed over a long period of time, and it does not mean that the koi recognizes its owner.

Notes on raising koi carp

1. The fish tank for raising koi carp must be equipped with a filtration system, and the water should be circulated at least 4 times per hour to ensure the water quality of the koi tank. clean.

2. Don’t feed the newly bought koi immediately. Let the fish adapt to the water temperature and quality first, and then start feeding after a week. Don’t worry that the koi will starve to death. They eat a lot and are more resistant to hunger. , usually only cause gastrointestinal discomfort due to changes in water temperature, and rarely starve to death.

3. The fish tank where koi is raised should have sufficient dissolved oxygen, and the stocking density should be controlled according to the size of the fish tank. If the number of koi is too large, the oxygen supply should be turned on. If you find that koi fish like to come out of the water to breathe, you need to turn on the oxygen pump to supply oxygen to the fish tank.
