if you're worried about the male killing the female then i would get a tank with a bigger footprint and make alot of hiding spots and some hardy dithers wouldnt hurt, my friend had salvinis as dithers with a small grammoders pair, saddly he didnt have them long enough to see if they work, but its worth a try
I can't upgrade but ill make some caves for the female that the male can't get into
