Question

my RES turtle has white patches on its shell...so i visited the site
http://www.austinsturtlepage.com and in the medical section the treatment for white patches was given,the treatment was:
Clean infected areas thoroughly with a strong, undiluted betadine, iodine or Nolvasan solution. Let the turtle air dry in a warm setting for about 45 minutes.
Apply a generous coating of Silvadene cream. Work into problem areas. Neosporin is also an acceptable alternative Leave the turtle dry and warm, ensuring that you do not over-heat, for 18-21 hours each day.
The next day, gently clean the affected area with a one of the previously mentioned solutions.Place them into fresh, clean water. Let them swim, drink and eat for
approximately 1 - 1 ½ hours.Repeat procedure from Step 1.This treatment performed daily or twice daily, should show you improvements within a week to 10 days. So i wanna ask that if the turtles are kept out of water for 18 hrs wont they die?and do i have to apply ....

the betadine solution on its shell and then immediately wash it after 2-3 minutes or i have to apply the solution and let it dry for 45-minutes?

Answer 1

its called shell rot and can be cured by either buying the medicine from a petstore so u can add it to its water or brush it on {there is various types} or take it to a vet

Answer 2

That procedure matches the advice in the veterinary literature that I have, and I have used that method succesfully.
It's called "dry-docking" and they don't die. They are not particularly happy during that time but it is the quickest and most effective way to get fungal infections under control. You paint the affected areas with Betadine after it has come out of the water for that day, before returning it to the dry tank, you leave it on to dry, don't rinse.
