looks like an amel nelson's to me...

you said it came from amel tangerines? do you mean hondos? if it came from amel tangerine hondos, then it's a amel hondo, just tricolor.

most hondos in the hobby arent exactly pure... really most milks in the hobby arent pure. people have mixed nearly everything together to manipulate pattern, color, tipping, and rececive mutations or in a few occasions, just didn't know better when early breeding started.

so imo, the only thing you can be 100% sure of is that you have an amel milk without knowing detailed info about it's heritage.

pretty snake regardless.
