a tank fish is a fish used to test the water. Because in the process of opening the new fish tank, there may be some problems that can not be noticed, resulting in the water is not well raised, so we need to try to use the fish in the tank first, if it can be raised alive, it shows that there is no problem in opening the tank, you can put the fish you want to raise. On the contrary, if the fish in the tank are dead, it is necessary to re-open the tank.
1, the fish has a problem: the tank fish must choose a good fish, and do not put only one, otherwise the tank failure may be the problem of the fish. Because novice fish farming often has a lot of things not to notice, some bad fish may die because of these aspects, and the fish with a little more solid skin is easier to live in the tank.
2. Problems with the water: The main problem with the failure of breaking through the tank is the water. Especially after several fish broke through the tank and died, it shows that the water is not well kept and the tank needs to be reopened for water. General water to raise trapped tap water, after drying to remove residual chlorine, so that fish can be raised well, but also pay attention to bacteria and filtration.
