1. Which kind of fish is easy to live in ordinary fish tank It is easy to live in ordinary fish tank. Generally, small fish are easier to raise than large fish. They have low requirements for water quality and like still water. Among the small fish, goldfish is the best kind to raise. There are many varieties of goldfish, but they are all wide-temperature fish, and their adaptation range to temperature is much wider than tropical fish, so it is less problematic to raise and looks beautiful.
2. How to raise fish in ordinary fish tanks1. Feeding: Feeding is the first step in raising fish in ordinary fish tanks. Fish have strong hunger tolerance, but long-term hunger is not the way, which will not only lead to stunted fish, but also become old fish. Usually, the fish should be fed three times a day, and each time the fish should be fed regularly and quantitatively, so as to ensure that the fish can be eaten within 5 minutes.
2, change water: No matter what kind of fish tank, no matter what fish are raised, change water is necessary. Changing water can improve water quality, but it will also cause certain fluctuations, so changing water should not be too frequent, and the amount of changing water should be controlled, usually not exceeding one third of the total amount of water.
3. Oxygenation: If the breeding density is relatively high, or the fish is large in size, it is necessary to oxygenate the fish to keep sufficient oxygen in order to meet the breathing requirements of the fish, otherwise it may float and even affect its survival.
