Red ear slider turtles in Fairdale, New York

Four red ear slider turtles looking for good homes. Rescued from negligent home. They are doing good and very active. Would like proof of proper turtle care supplies before adoption. I have a 135 gallon tank, but it is not large enough for all of them to stay in permanently. I will be keeping one of the turtles which has become blind from improper care. Only serious inquiries please.
