out of map turtles, diamond backed terrapins, and stinkpot turtles, which is always clawing at the glass? is it true that the terrapins always swim against the glass? do maps and musks not? does anyone know where I cam get an old turtle? their lifespans are too long for my situation so it would be better for me if there was one already in its 20s or teens. I already checks the shelters online.
