I have a friend at work who has several (I forget how many) Red Ear Sliders that she has had for about 8 years. She says they are pretty large, and wishes she could get rid of them so she could have room for Discus again. I told she should sell them, to which she replied, Who would want them that would give them a good home? And, "How much could I get for them"? I told her I knew nothing about turtles, but would try to help her find out. So, how much do you guys think several 8 yr. old turtles are worth each?
