1. The water quality is too poor: Mary fish may die because the water in the fish tank has not been changed for a long time, resulting in the deterioration of the water quality in the fish tank. The bacteria will multiply and infect them, causing them to die of disease. At this time, it is necessary to replace a quarter of the water in the fish tank and soak the fish tank with coarse salt to disinfect the fish tank.
2. Unstable water temperature: They may die easily because the temperature in the fish tank changes too much. They are a kind of ectotherm, when the temperature changes too much, their body resistance will decline, and they are easily infected and die. At this time, you need to add a thermometer and a heating rod in the fish tank to slowly adjust the temperature in the fish tank. Be careful not to heat them too fast here. If you heat them too fast, it will also cause damage to them.
3. High feeding density: They are easy to die. It is also possible that the feeding density is too high. When the breeding density is too high, they will fight and cause body surface injuries. If the wound is not treated in time, it is easy to die. At this time, it is necessary to fish out some of the fish in the fish tank and sterilize the injured fish with yellow powder.
Mary fish is prone to? The diseases Mary fish is prone to are enteritis, white spot disease and saprolegniasis. Enteritis is usually caused by feeding them too much. When they are found to suffer from enteritis, they can be treated by putting a certain amount of enteritis spirit into the water. White spot disease and saprolegniasis are mostly caused by poor water quality. When they are found to suffer from white spot disease and saprolegniasis, it is necessary to improve the water quality and bathe the diseased fish with erythromycin.
