They CAN, but the likelyhood is small.  Sometimes males loose all interest 
quickly.  I sometimes think they share the genes for fathering instincts with 
a certain bipedal mammalian species that has somehow spread its native 
habitat all around the world in spite of it.

Depends on the size of the tank.  Over 30 gallons, it is usually safe to 
leave the male in the tank.  15-30 gallons, it's about 50/50.  Ten gallon 
tanks, definitely pull the male.

They are too dissimilar to interbreed.  I would move the steindachneri so he 
doesn't kill the female borellii to get to the eggs.

>  4. How sensitive are borelii to pH and hardness? I mean, for breeding?

Mine won't breed unless I get the water soft and pH set at around 6.2.  I've 
heard folks say they have spawned them at 8 DH and 7.8 pH, so YMMV.
