[Symptoms] The sick fish's body surface is swollen, part of the scales open outward like a loose ball, the base of the scales is edematous, and its internal accumulation of translucent or blood-containing exudate, resulting in the scales standing up. When pressure is applied to the scales, a lot of watery liquid is ejected from the base of the scales, and the scales fall off. This is sometimes accompanied by symptoms such as slight hemorrhaging of the fin bases and skin, and swelling of the abdomen. The disease in tropical fish is mostly caused by frequent water changes.
If the fish is unfortunate enough to suffer from scaling, it is necessary to start changing the water in the tank, adjusting the tank's water quality, and replacing the old filter media to minimize the secondary damage to the fish caused by harmful substances in the water. Special attention should be paid when you notice that the fish's activity level has decreased and its food intake has decreased, because the scales will only be slightly lifted in the early stage, so if you can treat the fish in real time when you notice it, it is the most effective treatment period. You can use 50 liters of water to 1 gram of sulfonamide or [oral] murine agent, antibiotics to carry out the medicated bath, and then raise the temperature to 32 ~ 33 ℃, please pay attention to the color of the water in the tank, the cleanliness of the water and to provide sufficient air volume, if the water becomes cloudy within 24 hours, then you need to change the water immediately, and activated carbon filtration, and then re-do the medication again when the water quality is clear and stable. After 3 days of medicated bath, there will be obvious improvement, at this time, we can use the activated carbon in the filter tank to filter out the medicine, and then re-add the medicine will have very good results. (Remember to remove and discard the activated carbon after filtering out the medicine.) After one week, you can start to change 1/3 of the water and feed the fish with a small amount of food. After the fish's food quantity and scale condition are obviously smooth and normal, it means that the fish is back to healthy, although the edge of the scale frame will be a little burnt black brown, but it will not be affected, and it will return to its original luster in about 20-30 days.
[Prevention and control]
1. 1% salt water and 1% baking soda prepared into a mixture, dip the fish body for 10 minutes, many times after the drug can be effective. If in the dissolved water volume of 100 kilograms of aquarium using a low dose of splashing. Adhere to a number of also have therapeutic effects.
2. 0.1 grams of furacilin powder with gentamicin 2, and dissolved in the 80 cm * 50 cm * 40 cm aquarium, a long time bath has a certain effect, especially for the early stage of the disease of the sick fish effect is more obvious.
3. Baking soda plus salt can also be soaked, but the effect is slow.
4. UNISOL METHYLENE tablets crushed into the water.
5. Penicillin/chloramphenicol/gentamicin baths are also effective.
