Thin Bars are the most timid species, so you have the best chance with 2 of these then another species of Dat. I have had this combo before, and worked fine. Just keep an eye out.
I got a pair of 7" IT's that had been living together as a pair full stable all the time and had been together for a long time that were fine its doable.
