Fried fish scales are often caused by frequent water changes.
Fried scales manifest as swollen body surface of diseased fish, with some scales opening outwards like pine cones, edema at the base of the scales, and accumulation of translucent or blood-containing exudate inside, causing the scales to stand up. If you apply a little pressure on the scales, a lot of watery liquid will be ejected from the base of the scales, and the scales will fall off. Sometimes it is accompanied by symptoms such as slight bleeding at the base of the fins, skin, and abdominal distension.
Sickness of tropical fish is mostly caused by frequent water changes, which also means that there are bacteria in the fish tank. Once discovered, the water should be changed as soon as possible to ensure that the water quality is clean. The sick fish must also be fished out and maintained in isolation to avoid spreading the bacteria to other fish.
Sick fish should be soaked in a mixture of 1 part salt water and 1 part baking soda for ten minutes a day. Keep taking the medicine for about a week until it heals.
Due to years of artificial breeding, adult fish have unbalanced nutrition, especially lack of necessary vitamin supplements, resulting in reduced scale disease resistance. Do not raise fish at high temperatures and add salt for a long time, which will easily cause water corruption and bacterial proliferation. .
