Thank you for your reply!
Are you 100% sure she is a cooter? She was sold to the previous owner as a slider. Is there any way to treat the damage on her shell?
It might be worth noting that her shell was green when she was first bought, but because she has been mistreated it would seem the colouration has left her shell.
The green areas looks like algae to me but I am no expert. However, there is no algae in her tank.
Her basking temp is around 32 C and I feed her Fresh fruit and veg, Fresh meat and fish, King British all purpose food and Supa Turtle Food.
I have never owned a Terrapin before but I had to take her as her conditions were terrible. I have done my best since I adopted her and she has grown around a inch, maybe two.
Many thanks =]
