If the evaporation of water is less, the water needs to be changed regularly to prevent the aging of water quality.
No matter what kind of fish you raise, you should feed them regularly, but the small fish tank itself is not big, and there are not many fish to raise, so don't feed too much. Usually feeding once a day is enough, after feeding, the fish should eat in 3-5 minutes. If the temperature is relatively high, the fish have a strong appetite and can be fed twice a day.
Generally, the fish tank can be placed near the windowsill to maintain good ventilation and light, which is very helpful for the growth of fish, and can also play a role in improving water quality, equivalent to the effect of filtration.
