Yellow bellied terrapins

Question
Hi i have 2 yellow bellied terrapins, i brought them at the same time and have been in the tank together since babies, but recently i have noticed that the bigger 1 has been attacking the little one, and i noticed that the little ones right back leg he keeps in his shell and looks brown? do you have any suggestions on what to do?

Answer
Hello Chelsy,
I would definatly get him to a vet. It sounds like it is possible that he sustained an injury to his leg and perhaps it is getting gane greene
I would recommend that he gets to a vet ASAP as he can die from getting toxic.

Please if you can send me a pix.
