My experience with crayfish is limited, but the ones I have had seem to have done well. Which is nice, because other than make sure that they have a substrate deep enough for them to excavate, with rocks large enough for them to hide under, I haven't really done anything special for them. They will eat almost anything, and mine have been very happy with standard fish food that sinks to the bottom. (And the occasional slow fish.) If it's a temperate species, don't worry about heating its tank. Make sure it has filtration. They disappear for a couple days at a time; probably molting. I am no expert, but these basics seem to have had good results. And if your crays are like mine, if they aren't full size when you get them, they will grow pretty quickly.
