Hi. We are having a problem with my son's turtle. His scutes have got black (dirt) under them, I'm very worried it will turn into shell rot. I'm not sure if I should be using Betadine and scrubbing his shell. I don't want to stress him out if I don't have to. Just some background about him; we were given very bad advice from the pet shop and we're doing it all wrong for the first 6 months. We have been using this forum and website as a guide and have been doing everything possible for the past 8 months but our turtle never gets out to bask. We take him out in the sun every day for 15- 30 minutes, if it's raining, we still take him out until his shell is dry. We're in the process of getting a new dock that he might actually use which is in the mail. Apart from the black shell, he's a very happy turtle.
