It likes snails, shrimps, clams, small fish, pumpkins, cooked potatoes, rice scraps, bread crumbs, etc. Animal feeds can be fed in artificial breeding. The main varieties are fresh live small fish, snails and clam meat, etc. Gradually increase the amount of plant-based concentrated feeds, such as wheat, corn, soybean meal, etc., and do not feed animal feeds in high-temperature seasons.
