Fish farming must first have a fish tank, so for first-time fish farmers, how big the fish tank to buy is a problem. At present, there are two kinds of fish tanks on the market, rectangular and circular, which are more suitable for novices. In addition, the size of the tank and the size of the fish, if it is a small tropical fish, the length of the tank can be about 60 centimeters, if the arowana, the tank will be larger.
In addition to the size of the fish tank, what kind of fish to keep is also the primary issue for novices to consider. Generally recommend some relatively solid fish, and suggest that novices first raise cold water fish, such as grass gold, koi, etc. Tropical fish can also be raised, but some places are too cold in winter, it is best to have a heating rod to heat it, otherwise the water temperature is too low will lead to the death of fish.
If you want the fish to grow healthily, you must pay attention to feeding. According to the different types of fish, the choice of feed is not the same, do not want to trouble, you can also directly buy professional fish feed. Feeding must be regular and quantitative feeding, so that the fish form a habit, to the time will come to feed, dosage should be well controlled, do not let the bottom have too much residual bait, cleaning up is also very troublesome.
Changing the water is also an essential step in fish farming. And the habits of fish are different, some like new water, some like old water. For fish like new water, water should be changed frequently, usually every 3-5 days, and for fish like old water, it can be changed every 15 days. The amount of water for each change is about one fifth, if you change too much, it is easy to stimulate the fish body, affecting its health.
