Dragon eye goldfish do not need to use too deep water. Because the deeper the water, the greater the pressure. Because the eyes of the dragon eye goldfish will bulge out of the eye socket, not suitable to withstand too much pressure. Therefore, when breeding, the water depth should be controlled at about 25-30cm. When actually breeding, you can use some relatively shallow earthen pots to breed it.
Dragon eye goldfish has a strong ability to adapt to the environment, and the requirement for water is not high. If conditions permit, clean river water can be used for aquaculture. If it is not convenient to use river water, it can also use tap water which has been taken out in advance and aired for 1-2 days. When farming, water needs to be changed every 7-10 days or so. When changing water can not be completely changed, in order to avoid fish can not adapt, it is best to change one third of the water each time. When changing water, you can clean up the fish manure and food residues in the fish tank.
The dragon eye goldfish has a certain ability to tolerate low oxygen environment, but it can grow better in water with sufficient dissolved oxygen. When breeding, it is recommended to use oxygen pump to pump oxygen. If the concentration of dissolved oxygen in the water is too low, they will float up. In this case, oxygen must be used. If the breeding density is not high and the dissolved oxygen in the water is enough, it is possible not to use oxygen in this case.
