I do not second Lasius, at least ones that forage above ground. For one they are quite aggressive and territorial, not to mention fast growing. Might not be a problem at first but probably will eventually. I'd imagine subterranean species would do so long you provide them with enough substrate, sap sucking insects and keep the main Camponotus nest not touching the ground.
Formica sp. and Lasius neoniger seem to get along quite well. Their nests can be as close as a 1/2 of an inch together. Never have observed fighting between the two species. Although agression of lasius towards myrmica is quite common.
That is in the wild, where ants can do as they please, it's not uncommon to find a couple of species all nesting together (Leptothorax and Myrmica with many species like Lasius, Aphaenogaster occidentalis next to Formica, I remember one time MILTA found a Camponotus colony nesting to a Solenopsis sp.). We're talking about an 18 gallon closed tank here.
