Is my red ear slider's shell rotten and being eaten away?
Hi everyone, I'm a newbie to the forum. But I have an urgent question that I would like to ask all the expert in this forum. I want to ask if my red ear slider's shell is rotten and being eaten away. Below are three pictures that I have taken of my turtles. Can someone or anyone help me with my turtle. Thank you in advance.
