Do you need to wash a baby turtle? I currently am not using a filter since I only have 2-3 inches of water in his tank (He was sick and I was scared that he might not be able to swim well.) .I clean it out every other day though. Maybe every 3 days if I am feeling too lazy.

Every time I clean his tank I rub him down with a Qtip and rinse him under warm water. Is there a kind of soap that should be used? And should I be using some thing like a soft tooth brush? And how often should I clean his shell?
