The Dai's polypterus is known as a living fossil among fish.They have gills when they are young and can breathe air, so they can tolerate low dissolved oxygen water environment.In addition, they like to live in areas where rivers overflow, so it is necessary to install a strong filter in the tank.This provides them with a strong current environment.They are very ornamental and easy to raise, so they are very popular with fish farmers.
1. Feeding: Dai's polypterus is a typical carnivorous fish.During cultivation, fish, crustaceans and aquatic insects can be selected as food for feeding.Attention should be paid to providing them with nutrient-rich feed containing protein, fat, trace elements and so on, so as to achieve the goal of balanced nutrition.
2. Dissolved oxygen: They do not have high requirements for the dissolved oxygen content in the water body.Because they grow gills when they are young and can breathe air as adults, they can tolerate low dissolved oxygen in water.But when raising them, we should try to provide them with a body of water with strong currents, which can make them grow better.
3. Environment: Although they do not have high requirements for the environment, they prefer an environment with sufficient swimming space.Therefore, when feeding, it is best to choose the aquarium that matches them according to their size.
