A pair of Kribs in a Platy tank?

yeah I have them in with mollies
there's a few male platys in that tank too they are fine
I cant have the water super salty like live bearers can tolerate but it can
still be a little hard and salty, the kribs breed for me in those
conditions, my pH is pretty neutral though, I've read the ratio of males to
females gets lop sided the further in any direction your pH is from 7
so for a pair forming fish I try to keep it even.
I also have a few larger species of tetra in there and a recently pair of
gouramis which are maybe a little too agressive, I prefer fish that just run
away from the kribs rather than trying to stand thier ground (even if it is
only for a few seconds).
