How to treat swollen eyes of tropical fish?

1. Gill rot Gill rot is caused by myxococcus. When tropical fish are infected with gill disease, they move slowly, their body color fades, they lose their luster, their appetite is poor, their heads turn black, and their gills are covered with a layer of mucus and dirt. As the disease progresses, the outer gill filaments turn from bright red to white, and the gill filaments gradually rot and fall off. As the outer gill filaments rot, the inner gill filaments also begin to rot. The epidermis of the gill cover bone is congested, and the central bone necrotizes and falls off. In more serious cases, the entire gill cover begins to rot, eventually leading to death. Prevention and control methods: Put the sick fish and the healthy fish into another fish tank containing 3 parts per million furazolidone solution at the same time. When putting them in, stop feeding for 1-2 days, then feed a small amount of fresh bait, and gradually resume normal feeding. This method is relatively effective, and the sick fish can generally return to normal in about a week. If there are fish with severe diseases that cannot recover, they should be thrown away. Soak the original fish tank in 3 parts per million potassium permanganate solution for disinfection.

2. Red skin disease Red skin disease is caused by Pseudomonas fluorescens . Tropical fish will have a significant decline in physical condition after contracting red skin disease, with decreased appetite, slow movements, and swimming alone on the water surface. The fish's body surface will bleed and become inflamed, and scales will fall off. The scales on the sides and abdomen of the fish will fall off most seriously. The fish's gills will become congested. The fins will rot, and in severe cases, the epidermis of the gill cover will rot and fall off, and the gill cover will become transparent, and the fish will die in about a week. Prevention and control methods: Soak the fish and the fish tank in a 20-millionth potassium permanganate solution, or soak the fish and the fish tank in a 3-millionth bleaching powder solution, both of which can play a disinfecting and sterilizing role.

3. Scale erection Scale erection is caused by Pseudomonas aeruginosa. Scale erection is a highly contagious fish disease, but if tropical fish are strong and their skin is intact, they will not be infected with the disease. After tropical fish are infected with this disease, the skin of the entire fish body becomes rough, and the scales of the whole body stand up and spread outward. Fish infected with this disease will also have complications such as rotten gills and bleeding at the base of the fins. Sick fish have difficulty breathing, slow movements, and loss of appetite. If not treated in time, it will cause a large number of deaths.

4. Symptoms of white spot disease: The diseased fish look dull, often wash themselves in the water or scratch themselves on rocks, their body is covered with white or light grey spots, and the diseased fish are cross-infected and twice infected.

There are two common pathogens: one is similar to the multi-sprouted Ichthyophthirius in freshwater, and the diseased fish has white spots on its body surface; the other is the Oval Giardia, and the diseased fish has light gray spots on its body surface and is difficult to cure.

Prevention and treatment methods:

① Raise the water temperature to 30℃. The parasite cysts will rupture due to the increased water temperature and automatically leave the fish body. This method is effective for fish infected with white spot disease for the first time, but it is not effective for fish infected for the second time. It must be treated with medicine at the same time.

② Soak the new bricks in urine for 24 hours. After drying, put them in the aquarium. After more than 10 hours, the small white spots on the fish's body will swell. After more than 10 hours, you can see the small white spots on the body surface falling off one after another. The effect is good.

③ Soak the sick fish in fresh water, which is a mixture of 9 parts fresh water and 1 part sea water. The immersion time is 0.5 seconds to 2 minutes. Pay attention to the degree of adaptation of the fish. If the fish is breathing nervously, move it to sea water immediately.

④Put 10 kg of seawater into a glass tank, add 0.05 g of copper sulfate, oxygenate, and soak the sick fish for 5-8 minutes. After 24 hours, the white spots on the body surface can be seen falling off. This method is more effective for fish that are sick for the first time, but not obvious for fish that are infected for the second time.

5. Symptoms of fin rot and skin rot: The fins of the diseased fish are incomplete, the scales on the body surface fall off, the skin rots and has superficial ulcers. The cause of the disease may be that the marine ornamental fish fight with each other for territory, or they are not adapted to the new water, resulting in injuries to the fins and skin, leading to bacterial cross-infection, especially when new fish are placed in an aquarium with existing fish. This situation is more likely to occur.

Prevention and treatment methods:

① Put 2 cephalosporin tablets or 4-5 furazolidone tablets in 10 kg of sea water and soak the diseased fish for 10-15 minutes.

②Put 0.2g potassium permanganate in 10kg sea water and soak the diseased fish for 5-10 minutes.
