Q:How do the fish in the tank keep the fish together?
Turn the suction down a bit or place a net in front.Oxygen pumps do not open for 24 hours all day long! Usually in the morning, afternoon, each charge 2 hours or so, the evening charge for a while, if the weather is overcast, then open a longer time. If you do not have a filter, you should always change the water for the fish, preferably 3 or 4 days at a time, with 1/3 of the total water, but it must be dried! The temperature of the water should be similar to that of the fish tank! Every time you don't feed too much, clean up the excreta in the fish tank.
