Mine are pretty hardy little guys. I had them in a 10 gl tank with 5 gold tetras and a tiny red flame gourami. I had a whole bunch of cabomba in half of it. I was keeping them there temporarily till I got my big 75 gl. ready for them. It currently had 16 tiger barbs that would have surely killed them, but also had pretty hard water.
Since this weekend though I've given the barbs away, changed the water, and they're now in the big 75gl tank with their other tank mates, along with 5 pretty large blue gourami's. They all seem to be doing very well. The rams are pretty brave little guys and come up to the glass when I walk buy asking for food. They don't seem to be intimidated by the large gourami's at all and swim right along with them. The tanks pretty lush with swords, Cabomba, and Anarchis, with a few caves and things for em. They like swimming around though and I see them out in the open space quite often. I plan on getting some bottom feeders pretty soon, but I want to change the gravel to sand... which will be a pain.
So yeah... pretty hardy little guys (aside from what most info sites will tell you), get along with most fish, and do like lush tanks with places to hide. They did well for the first month in the 10 gallon as well... but I would got a bit bigger.
