1, reason: When the water quality in fish tank is too poor, the germ in fish tank can breed in great quantities. When the bacteria multiply to a certain extent, they will infect the grass turtles, causing them to rot their skin.
2. Treatment method: First, replace a quarter of the water in the fish tank to reduce the concentration of bacteria in the water and improve the water quality in the fish tank. Then the sick tortoises are taken out, and erythromycin is smeared on the sick tortoises to sterilize the body surface of the sick tortoises.
feeding density 1. Reason: When the number of grass turtles is too large, the feeding space in the fish tank will be insufficient, and they will fight for living space, resulting in body surface injury. At this time, the bacteria will enter their bodies along their wounds, causing rotten skin.
2. Treatment method: First, take out some grass turtles and put them in another fish tank with similar feeding environment to reduce the feeding density. Then take out the sick grass turtles, smear yellow powder on them, and treat the wounds.
temperature change 1. Reason: Grass tortoises are poikilotherms. When the temperature in the fish tank changes too much, their body resistance will also decrease. At this time, it is particularly susceptible to infection, leading to decay on the surface of the body.
2. Treatment method: Put a heating rod and a thermometer in the water, turn on the heating rod and slowly adjust the temperature in the tank to 25-28 ℃, and leave the heating rod and the thermometer in the water to maintain the constant temperature in the fish tank. So they can recover slowly.
