If you raise fish for the first time, you need to open the tank. Opening the tank to raise water is a process, in which you need to cultivate some beneficial bacteria. If the tank is not opened properly, the nitrification system has not been established, and there will be bubbles in the fish tank. At this time, strengthen the filtration, and change the water regularly. You can also consider putting some nitrifying bacteria. Establish a nitrification system as soon as possible.
Usually, keeping tropical fish will control the temperature of the fish tank, but cold water fish will not control the temperature. If the water body warms up with the environment, the dissolved oxygen in the water will be very low, and some bubbles will be produced. If it is not solved in time, the fish will lack oxygen, which is not conducive to its survival. At this time, first of all, we should pay attention to cooling, and secondly, we can fill oxygen.
The water for fish culture should not be too fat. If too much feed is fed at ordinary times, what the fish cannot eat will become residual bait. At the same time, there will be a large amount of excrement. All these will cause the water quality to become fat. Once the water body becomes fat, microorganisms will multiply in large quantities. Due to the imbalance of bacterial flora, a large amount of foam will also be produced. Therefore, it is necessary to control feeding and clean up the dirt at the bottom of the tank in time.
Most fish have a layer of mucous membrane on their body surface. If the fish get sick, the mucous membrane will fall off, and a large amount of foam will be produced in this process. In view of this situation, it is necessary to treat the fish in time, in addition to changing water and warming up salt, you can also consider medicinal bath, but we must pay attention to the concentration and soaking time.
