Method for cultivating ornamental fish
Cultivation methods of ornamental fish:

First, carry water in advance. The first thing to raise ornamental fish is to raise water, and fish cannot live without water. Inject tap water that has been dry for a few days into the fish tank, and then install oxygen-increasing equipment and filtering equipment to see if it can work normally. Then pour in nitrifying bacteria, put some fish food, turn off the lights and explode oxygen to establish a nitrification system. Under normal circumstances, the fish tank will be turbid first, then clear, and the water is a little sticky, indicating that the water is well maintained.

Second, feed regularly. After raising the water, you can raise fish. Need to feed regularly, usually once a day, every time until seven or eight points are full. The way to judge whether a fish is full is simple. Just watch carefully and see the reaction speed of the fish after feeding. If you are not interested, it means that you are full and don't feed any more. If fed too much, it is easy to get enteritis, which will affect its health.

Third, pay attention to changing water. Fish farming must change water. For some fish with low water quality requirements, it will not affect their survival without changing water, but they often don't grow long. Usually it should be changed every 3-4 days or once a week. If the filtration system is good, change it once every half month, and change it by about one fifth each time. Too much will irritate the fish. And be sure to change the trapped water, not the tap water just connected.

Fourth, maintenance during illness. If the ornamental fish are unfortunately sick, the protection situation will be different. First, change the frequency of water change, once every other day. In addition, after changing the water, the temperature should be raised appropriately to accelerate the metabolism of fish and improve the resistance. Finally, you need to add a little salt to prevent bacteria from invading the fish.
