CATDOLL : CATDOLL: What disease does the guppy have?

This is bubble disease: Symptoms: Many bubbles of different sizes appear on the body surface, fins (especially the caudal fin), gill filaments, and intestines of the diseased fish. The body becomes unbalanced, and the fish floats on the water with its tail up and its head down. The fish breathes rapidly, is unable to swim, and is unable to eat. There are many spots of bubbles on the caudal fin, some as big as millet grains. In severe cases, there are not only bubbles but also red lines on the caudal fin. If the fish is injured again, the wound will become red, swollen, ulcerated, and infected with disease, resulting in the caudal fin having no caudal fin membrane and exposing fin bloodshot. Treatment: ① When the disease occurs, add new water immediately, remove part of the original water, or move the fish into an indoor water tank or new water and let it rest for about 1 day. ② Use an air pump to drive out over-saturated oxygen in the water. ③ Control the water temperature and light ④ Slow down the pace of releasing new fish. I wish your fish a speedy recovery.

The burnt tail of guppies may be caused by polluted water. At this time, you need to replace the water for the guppies immediately, and then apply fish disinfectant to the tail. It may also be caused by attacks by other fish. At this time, the injured guppies need to be isolated and maintained, and some salt should be added to the tank for the injured guppies to soak and disinfect. It may also be caused by too high water temperature. At this time, the maintenance water temperature needs to be adjusted to about 25 degrees.

The most likely possibility is a parasite on the body surface. If scales appear, it is definitely a parasite.

From your pictures, it seems that your guppy has a burnt tail. In most cases, the burnt tail of guppies is caused by the over-acidity of the water in the aquarium. They prefer slightly alkaline water, and the pH value is generally controlled between pH7.2 and 7.4. Most fish lovers raise guppies in a grass tank, although a grass tank is definitely more beautiful than a bare tank in terms of ornamental value...
