If you mix threadfins with a more aggressive species, even another rainbow, they may not do very well. They aren't exactly the most outgoing fish.
Believe what Six has to say; it is excellent advice. I tried to keep the Threadfin rainbows 2 other times in mixed tanks and lost them - not all at once, but one by one over several months. But I'm willing to learn and decided to give them another try. Now I have a group of 14 in a dedicated tank and they are doing well. They do not hide in the sides and corners. Their colors are amazing, and very beautiful to see them flaring. It is wonderful to see the difference. No one competes with them at feeding time. And when I reach to open the glass top for feeding they all come charging to see me.
PS. It is a 20H. I do have a few Ottos and Amanos for clean-up; along w/ 3 Peacock Gudgeons to give the bottom level some activity!
(However, I am working on moving some fish around and placing them into a 20g long, just to give them more room to race about and flare at each other.)
