Recently, the fins of parrot fish and scavenger raised at home have become a wisp. What happened? How high should the fish tank be heated this season?

First look at the temperature. The temperature should be too low for the fish to move. Don't put the fish tank next to the window. Cold fish can't stand the problem of large temperature difference between morning and evening. It can be easily solved by adjusting the heating rod to 26-28 degrees.

Fish don't eat feed, and no matter how big and medium-sized fish are, they are lucky to clean the fish like parrots, and they can't die without feeding for a week. The easiest way is to go hungry. Feed them today, stop eating tomorrow, and scramble to eat when they are hungry again and again.

Just feed the parrot red feed.

Usually, we should pay more attention to the activities of fish, including shrinking fins and white and hairy bodies. These are common things in autumn and winter. Generally minor illnesses and injuries can be solved by changing water, heating and adding salt.

Then change the water. If the filter cotton is dirty, it should be cleaned and replaced regularly. It is suggested to pump 1/3 fresh water every 7- 15 days, and the water to be changed should be intercepted in advance.
