The fish recognizes its master. It should be noted that fish do not recognize their owners in the true sense. What makes them active and excited is that every time the owner feeds them, it is the food that attracts them, not the owner himself. This is a conditioned reflex. , so that you can make some reactions according to the instructions. If the fish will swim quickly in the water or even roll when the owner passes by the fish tank, it means that the fish knows the owner.

How to raise fish:

1. It is recommended to choose a container with a larger diameter to slow down the deterioration of water quality and enable the fish to grow better.

2. Under normal circumstances, feeding once a day is enough. The principle of feeding fish is to feed less.

3. The temperature and amount of water are crucial. The new water we change can be one to two degrees higher than the old water. This ensures the living environment of the fish. Changing the water is not a complete change. It is best not to change the amount of water more than one-third of the original amount each time.
