Parrot fish peeling may be caused by saprolegnia. Pay attention to changing the water during daily feeding. If the water quality deteriorates quickly, change it once every three days, about a quarter each time. The temperature before and after changing the water should be be consistent. Also be sure to wipe off any dirt on the parrot fish. In addition, the dissolved oxygen in the water body must be sufficient, otherwise the fish will be unable to breathe. It is best to use an oxygen pump to provide oxygen throughout the day. It is best to buy medicine to treat saprolegnia and give the fish a bath if the condition does not improve after three days.

What should you pay attention to when raising parrot fish:

1. Feeding. Parrot fish can also be regarded as a tropical fish with a wide eating intestine. When raising parrot fish, you must provide them with adequate food. Because if the parrot fish is not nutritious enough, its body color will gradually fade. However, if you feed too much, the water quality will become turbid or the water color will turn yellow.

3. Water quality. The water quality in which parrot fish are raised must be guaranteed, and filtration equipment is absolutely necessary, unless you raise them at a very low density or do not feed them at all. It is best to equip the upper filtration system with trickle equipment and the lower filtration system with a wet and dry separator.

3. Water temperature. If you want to feed parrot fish, a water temperature of 22 degrees is enough. But it must be kept in good condition, with each fin stretched out and glowing red. Then, our water temperature must be at least 30 degrees, so as to ensure good hair color of parrot fish.
