I bought six of these guys from a seller in the UK. I had assumed they were going to be wild type X.laevis but they didn't look quite right, couldn't really put my finger on it but after chatting to the seller I found out that the adult males are 2.5" and the females 3" which puts them well below the size I would expect X.laevis to be. If somebody could id them for me that would be great so I can give them the optimum care. The difference in the frogs belly colouration is down to the substrate they were kept on and does change according to the seller.
