They'll be fine with nothing. Just de-chlorinated water. It's kind of tempting to put a plant or a PVC pipe or something in there in case they get "bored", but it would be best to leave plants and hides in the tank while it's cycling so that some of those nitrifying bacteria can colonize on them as well. Most of the bacteria will colonize in the filter media and in the filter itself, but at least a small amount will live on plants, on rocks, and pretty much anywhere with a decent amount of surface area. That's why, in addition to my good old hang-on-back power filter, I have a pretty big sea sponge in my tank (held down with a rock that I stuffed inside). It provides a huge amount of surface area for bacteria but it doesn't get super dirty since there's not water being pulled into it. Plus, it looks nice, and my axolotls like to climb on it!
