Hard to say. Let the pictures coming. I guess from coloration Male, but the bump is unnoticable on the most pictures. I can see it slightly on pic. 3 and 1
I just realized you said he's a Mitsio... where did you get him from? A reptuable breeder? I've never seen a young Mitsio those colors. However, Mitsios seem to throw off a lot of brilliant reds when they're youngsters...
He looks a lot like an Ambilobe to me. Yellow body... dark blue bars??? other hints of other colors...
