He looks like a rutilus at this point, but I'm hesitant to make that call, as I've not seen many this small, as his shape looks Indochina. I suspect that those two species are nearly indistinguishable at this small of a size.
I'd like to see it grow out some before making the final call, as this guy could be quite instructive to all of us as to which species it is, and how to tell indos from ruties at this size.
Fwiw, I'm leaning Indochina, but I'm not sure yet.
