1. Common animal feeds for snappers include small fish, shrimp, earthworms, snails and mussels, and ground fish and shrimp meat, etc. These foods contain high protein and nutrients, which are helpful for the growth and development of snappers. Plant feeds, on the other hand, include algae, water plants, moss, vegetables, fruits, wheat bran, soybean dregs, etc. These foods contain more vitamins and trace elements, which help to improve the resistance and immunity of snappers.

2. Snappers do not require high water temperature, they can grow in water temperature from 0 to 32℃, but the most suitable temperature for them is 25 to 30℃. Snappers have high requirements for water quality, preferring to move in clean and fresh water, and the PH value of water is best kept between 7.5 and 8.0. Therefore, when breeding snappers, you need to pay attention to changing the water regularly to keep the water quality fresh.

3, in terms of feeding, snappers can be fed once a day when they are young, and once every 2 to 3 days when they are adults. When feeding, you can put the food in the water and let the snapper try and ingest it by itself, or you can use chopsticks and other tools to gently bring the food to the snapper's mouth. It should be noted that the environment should be kept quiet when feeding to avoid affecting the appetite and mood of the snappers.
