Shares exhibit with Pelusios chapini so could be difficult to ensure the ID. But comparing the head colour with the tank signage, I would say that all the specimens that I saw here are P. carinatus
No, there should be 3 Pelusios chapini in the tank. One turtle is much much larger than the others. Following wikipedia, the chapini can grow 15cm larger than carinatus. So I'm pretty sure that one is easy to find and that's how to make sure you have the Pelusios chapini on photo too
Thanks. I don't remember to have photographed any especially large, tough this is not a reason for exclude the two not full grown specimens of chapini.
