Same as the regular ones, it depends on the tankmates and on the tank size. The problem with keeping a cray in a 10 gallon with tankmates is that the crayfish is ALWAYS just around the corner, and it's not good for fish to be perpetually hunted. In a larger tank this would not be as much of an issue, but again it depends on the tankmates. Another reason, that I forgot to mention, that barbs are such great crayfish tankmates is because they have a little chip on their shoulder. I'm not saying cherry barbs are aggressive, but they are barbs and have a certain.....tenacity. While they respect the cray, they aren't afraid of it. Tank mates that fear the crayfish will get stressed by it and develop problems.
