Maybe someone told you that the E.a. are CB, but I do not believe it. Did the person show you any juveniles, or describe to you the conditions used to breed them? I doubt it.
Genuine CB animals are rarely sold as adults (normally CB are juveniles), and E.a. has very rarely been bred. The upper of the two animals looks to be in poor condition, would also not be the case if it were CB.
I haven't seen a lot of people who keep WC E.a. There are a few, but most of them have been imported years ago.
