Does the oxygen pump for fish keep running?
My small fish tank is always open, anyway, power consumption is not much
Not necessarily. There is filter work, the cylinder is small, do not always open,
If it's dense, it should be turned on
It depends on how much fish you raise, and if you don't have any oxygen, you die immediately! ~ you need to keep the fish tank 25 degrees in winter, and the poison in the tap water needs time to evaporate. Otherwise, the fish will die easily! ~ tap water should be placed for 7 days, you can fish, change water once in 1 weeks, change 2/3. Leave 1/3 old water. Feed the food can not feed too full to eat fish, do not know, will die, let the fish alive, love travel. Feed a half full can, but does not affect the water quality is the best filtration water intensive feeding hub ball oxygen, fish tank, fish less. You don't need to use oxygen. Just fish not greedy, keep the less the higher the survival rate. When buying fish, choose white spots, no disease. Goldfish. Select a group of fish, which are relatively large, relatively dynamic fish, high survival rate. The new fish must be observed in a few days and then raised together to prevent infectious diseases, according to what I said. Fish, very good to keep
