1. Bask in water. Before buying grass goldfish, you should first find a sunny place, and then fill the fish tank with water and dry it for one to three days to let all the chlorine in the water volatilize. If you don't go through this step and put the fish directly in the tank, then the fish will die in less than a day. However, if you haven't dried the water in advance, you can keep the fish you bought in the water you brought back for a few days.
2. Add salt. Putting some salt in the water where grass goldfish are raised can not only have a sterilizing effect, but also inhibit the growth of bacteria in the fish tank. However, you must remember not to add some so-called disinfectant water to the fish tank, or a potion for fish treatment, because those things are fooling, and there is *** and even the dosage is not well controlled, which will kill the fish.
3. Feeding. We all know that any creature in the world will die if it doesn't eat, so it's the same with fish farming. Everyone should feed the grass goldfish regularly to make its body strong. Under normal circumstances, live small insects are the favorite of grass goldfish, and they are nutritious, but they cannot be fed every day, and they are generally fed once every five days.
