The main reasons for the bloated belly of parrotfish are as follows:
Indigestion: If you overfeed parrotfish, they may suffer from indigestion, which leads to a bloated belly. In this case, parrotfish may often stay at the bottom of the fish tank without moving, and may even have diarrhea.
Pregnancy: The bloated belly of parrotfish may also be due to pregnancy. Usually, about half a month into pregnancy, their bellies will start to grow larger, and their genitals will also become more prominent.
Intestinal Diseases: Bacterial infections may cause parrotfish to develop intestinal diseases, such as bacterial enteritis. In this situation, the mental state and appetite of parrotfish will decline, and their bellies will also become bloated.
Water Quality Issues: If the water quality is poor, it may cause the internal organs of parrotfish to become infected or inflamed, resulting in a bloated belly.
Overfeeding: Overfeeding can also lead to indigestion and a bloated belly in parrotfish.
Treatment Methods:
Stop Feeding: If the bloated belly is caused by indigestion, the first step is to stop feeding and change the water in the fish tank in a timely manner.
Medicated Bath Treatment: You can add an appropriate amount of oxytetracycline or gentamicin to the water for a medicated bath treatment until the belly of the parrotfish returns to normal.
Observe the Condition: If the parrotfish has enteritis and its body color remains unchanged, you can sprinkle norfloxacin into the water for a medicated bath treatment; if the body color turns dark and there are symptoms such as fin clamping and tail rot, then you need to use oxytetracycline, copper sulfate, and salt for acute anti-inflammatory treatment.
Keep the Water Quality Clean: Regularly change the water and use a water quality regulator to ensure that the water quality is clean, which can effectively prevent the occurrence of a bloated belly.
