I have come across many examples of Lasius flavus sharing a rock with Laisus niger, Myrmica and Formica fusca.
Each time they seemed calm at first, but I noticed that if ant of one sp wandered into the area of ground (that I have exposed) of another sp, they would get very upset and fight, so each different ant sp must keep them selves to them selves if possible.
I have also found Myrmica sharing a mound with Lasius flavus. But, if I damage the mound, the Myrmica start killing the L.flavus workers after a few minutes.
If you were to try this in captivity, you need loads of space to prevent conflict.
