? They can eat small fish, but not all small fish. They can only eat fish that are smaller than them. They can't swallow fish that are too big. In addition, small fish are not their favorite food. They only consider eating small fish when they are very hungry or when they are fed food they don't like. Therefore, when feeding them, it is better not to feed them small fish as food, but to feed them some live baits such as mealworms.
? Manlongyu eat vegetables. They are omnivorous fish. They can eat a lot of food, such as meat, vegetarian and fish feed. Vegetables are a kind of vegetarian food, so they can be used as their food. Vegetables are rich in various vitamins and cellulose. Vitamins contribute to the absorption of various nutrients in the body, while cellulose contributes to digestion. So you can feed them.
Of course, vegetables also have disadvantages. Vegetables are relatively large, and they need to be cut up before feeding, otherwise the fish can't eat them. Some vegetables need to be cooked before feeding, because their taste is particularly bad, if not cooked, the fish will not eat. Vegetables are still relatively low in nutrients, if they are fed vegetables for a long time, it will lead to malnutrition, so vegetables are only suitable for feeding them as supplementary food, staple food or to choose animal feed.
