We had tried breeding our original female to our original male and after a month, nothing. So she's been living by herself for a few weeks now and we just picked up an albino male in hopes of getting her to breed. The female is 40g and of an unknown age. The male is 30g and is defiantly over 12 weeks but not too old (we got him from a friend)

Would it be ok to put him in with the brown female and just watch them really closely to make sure there is no aggression, or should we not put him in with her and take other steps to introducing them?
