Do they recognize each other, if they are separated from each other for a short time (match for life)?

Although you might have kept 2 terrapins/turtles together for many years when they come here they do not stay with each other. If they are separated for a few weeks and then go back together they don’t show any signs of remembering each other. Terrapins/turtles are by nature solitary animals; they will happily live together with enough space but they do not form friendships or relationships.
