Grass goldfish can actually get to know their owners. The memory of goldfish is mainly related to the brain structure. The larger the fish, the better the memory. Most grass goldfish have relatively large heads, so the memory is better, and they will naturally remember and recognize their owners. For example, when the grass goldfish sees its owner approaching and feeding, it will show the behavior of swimming around. This is a reaction of the grass goldfish recognizing the owner.
