Good Afternoon Everyone!

I am looking for some guidance today. I have a male Mochi (enchi x mojave) that I have been putting with my females during this breeding season. This is my first year breeding, and to add this is my only male. I have one other male but he is only 150g at the moment, the Mochi however is sitting around 950g. For some reason, he only locks up when I place him in the tub with my albino female? He won't make as much of an attempt to try either of the 3 other females I am trying with him. He had bred last year when I let my friend borrow him because my females weren't ready, but so far he only locks up with my albino. Any tips on getting him to breed with my other females? Thanks a bunch in advance for your suggestions and help.
