1. Reason: The loss of swim bladder of butterfly carp may be due to the large temperature difference, which stimulates the swim bladder and causes the swim bladder to fail to work normally. This situation is more common in spring and autumn, because the temperature difference between morning and evening is large in spring and autumn. Also, when changing water, the temperature difference between new water and old water is too large.

2. Treatment: This irritating swim bladder is better treated, and the breeder first fishes them out for rest. Secondly, keep the water temperature constant with a heating rod. Finally, the oxygen pump can be used to continuously supply oxygen to the fish tank. As long as they live in a comfortable and stable environment, they can generally recover.

1. Reason: The loss of swim bladder of butterfly carp may also be caused by indigestion. For example, if the breeder feeds too much indigestible food, it will cause their intestinal blockage, which will squeeze the swim bladder and make them unable to work normally.

2. Treatment: The breeder can raise the water temperature to about 25 ℃ first, and high temperature can promote the metabolism of butterfly carp. Then use Sanhuang powder or compound berberine medicated bath to prevent fish from being infected with bacteria. Finally, feed some probiotics or digestive drugs.

1. Reason: The swim bladder of butterfly carp may also be infected with bacteria, which is mainly caused by unclean food.

2. Treatment: Breeders need to fish them out immediately and raise them separately, and lower the water level to avoid them turning over. Keep the water temperature between 20-25 ℃ and keep the water clean. If butterfly carp roll over seriously, the breeder should make a splint for them to avoid roll over.
