Bn's Breeding At Sub Tropical Temps

[jonnyf84]

I am setting up a new tank for a species of a rare type of xiphophorus that needs cooler water (74f max, ideally 73f) I would like to put my breeding trio of BN's with them but i have never tried breeding BN's in cooler water.

Will BN's breed in 73f?

they should be fine in that

thanks, i know they will live quite comfortably in those temps but i wasn't sure about actually breeding, i guess after generations and generations or captive bred stock they may have become more tolerent to a wider range of temps.
