Matters needing attention in fish tank culture:
1. It is very important to change water properly and raise fish water. Usually pay more attention to the water temperature of the fish tank, whether the water is too turbid and whether the smell of the water is unpleasant. Just change the fish tank once a month in autumn and winter. When changing the water, the damage to the fish should be as small as possible. Clean the bottom of the water tank, and then inject fresh water.
2, timely treatment, if sometimes sick fish appear in the tank, if you think it can be cured, you can continue treatment. It is best to raise separately and conditionally. If the fish is not cured, it can be fished out and released. This is better, so we must pay attention to the situation of fish and find it in time for timely treatment.
3. Correct arrangement in the storage tank. Generally, fish farming in tanks is mainly for viewing, so some stones, fine sand and some aquatic plants can be put at the bottom of the tanks, and some aquatic plants can also be planted on the water surface, which can not only provide necessary oxygen for the fish in the tanks, but also increase the activity of the fish.
4. Choose the fish you want to raise. Fish farmers can choose the fish to raise according to their own preferences. Generally, there are many goldfish indoors, but there are also other fish. Try to choose the one with strong vitality and moderate size, which is not only easy to feed, but also not afraid of having too much influence on the space in the cylinder when it grows up.
