The tortoise has long hair on its head.

1. Don't let the tortoise stay in the water yet, just feed it regularly every day. At other times, try to keep it dry and let it bask in the sun (don't bask for too long, it's summer)

2. Then use the magic weapon: chlortetracycline eye ointment! Apply it once a day and several times. Dip a small cotton swab (I use a toothpick wrapped with a little cotton) in chlortetracycline eye ointment and wipe the white spot hard. At this time, the tortoise should shrink back, don't be soft-hearted, and pull it out to continue rubbing.

3. Disinfect the turtle tank with potassium permanganate solution. Never let bacteria breed in the turtle tank.

4. After getting better, change the water frequently and disinfect the turtle tank frequently. In fact, there is no need to soak the turtle with potassium permanganate ~ Every time you change the water, soak the turtle tank with potassium permanganate solution, wait for ten minutes, pour the potassium permanganate water and replace it with new water.
