He definitely looks like he has Ambilobe blood in him but since you have no information about his bloodlines, there is no way to be sure if he is a pure Ambilobe or not. He looks like he will develop nice coloration but please remember that you won't be able to definitely determine whether he is a pure Ambilobe or not.
I do not think him pure Ambilobe, but I do think him closer to that Locale than any other. His dorsal spines do not seem to have any red-orange in them, and that is why I think him not 100%.
Yes i agree. In my last posts i have mentioned the same thing. You cannot label something that you are not for sure on. Unfortunatly i have failed to mention this in this post.
