Mary fish will not recognize their owners, and ornamental fish cannot recognize their owners. Their IQs are very low, and they will not recognize their owners like cats and dogs, let alone have feelings for their owners. However, after getting along with their owners for a long time, They will be familiar with the owner's voice and be able to distinguish the owner, so they will have some conditioned reflexes and can interact with the owner, but this is not recognition of the owner in the true sense.

Precautions for raising Mary fish

1. When raising Mary fish, you need to ensure that their living environment is stable. Breeders need to keep the water temperature and quality of their lives stable. If possible, it is best to install a heating rod and filter. When changing water, you should also pay attention to the temperature difference between the new water and the old water.

2. Although Mary fish have lively personalities, they are relatively timid. Breeders need to ensure that their living environment is comfortable to avoid fright.

3. Mary fish is an omnivorous fish, and breeders need to use a variety of foods to feed them. Breeders can feed some aquatic plants, algae, moss, etc., as well as some red worms, mealworms, fish worms, water earthworms, etc., and can also choose some synthetic feeds. This can not only ensure their nutritional balance, but also avoid the situation of a single diet.

4. Mary fish are small fish, so their food intake is not very large. Breeders need to feed them small amounts of food frequently to ensure that they have enough food and avoid indigestion. Breeders can feed 2-3 times a day, and each feeding can be eaten within 5 minutes.
