It really is a bit difficult to determine exactly what morph Tango is. You say his eyes are red. More specifically, what is the color of his pupils? If it's black, he is probably either a hypo or a normal that just doesn't have alot of black. If the pupils are red/pink, then he is an amel. If the color is sort of half-way between black and red/pink, than he might actually be an ultramel. Here are some examples showing the eye and pupil color of a normal, a hypo, an amel and an ultramel. Hope they help.
