Its unequivocally 100% male salvini, in my opinion.
I also agree with Freaky Jason, the liklihood of a salvini breeding with an aequiden of any species is so low its not worth mentioning. The possibility of a spawn resulting in viable offspring is even lower(if not impossible).
BobTheFish: Its too bad you gave up on them based on their coloration. Its definitely true that the real bright yellows are breeding dress, but in my opinion their coloration is about the most boring thing about them. Very, very cool fish to keep in my opinion.
