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).

I have Diant Danios, Kribs, Keyholes, Platys, Otos, Farlewella and
corys with no problem. I tried to get a pair of Kribs, but my "male"
matured into a female. They all do very well together with no
problems. The Danios, while not overtly aggressive, do tend to swim
through, rather than around, other fish. They were all added over a
number of months while young. I tried to add a few more cute juvenile
Platys only to find the more aggressive Krib biting at the bag. I
moved the Platys to my White Cloud tank and will try again when they
are bigger. Needless to say, with this mix you are unlikely to have
fry survive. My Platy's have bred and the fry never survive more than
a day or so.

Kribs' can get very aggressive if breeding. I change the water each
week which keeps my Krebs' colours very bright! They are beautiful
when in full colour. However, the #1 Krib will go into a cave on
occasion and dart out viciously protecting an area around the cave.
The other fish do not appear afraid and the Krib appears only to push
the fish (especially the corys) around. The corys always give way,
but they have short memories so they head on back. The "push" does
seem quite violent, but so far none of the others have been injured.
As I said, I have two females so things may get touchy with a real
pair. You would need to research the size of the Krib's territory to
ensure that there is enough room for other fish to swim about without
constantly harrassing the Krib.

I am a beginner and have never had problems with my Kribs. My
research suggests that they are sensitive to ammonia and nitrates but
otherwise fairly adaptable within reason.
