I bred one of my males at 500 grams, he stayed on food and did just fine. His clutch also came out with 8 healthy eggs (though they didn’t all make it through incubation, I have a thread open on that) but yeah you may run into some fertility issues from a younger male.
You could also wait a little longer and let him pack on a bit more weight, but then your female may start absorbing her follicles if she doesn’t have a male in with her soon enough.
It’s really your call though, so do whatever you’re comfortable with!
