In the 10 gallon, there is sandy substrate underneath the rocks, and those swords only have very few roots coming from the base, so there's not a lot of hold. For now they are in and I'm just going to leave those alone unless I see them floating at the top. Their plant brains will tell them which direction to extend the roots, hopefully. No big fish in there to knock them around, either.
On adding substrate, yes, though if that is enriched substrate [Flourite, Eco-complete or similar] might be a bit messy in the water for a few days, but not an issue otherwise. I often add gravel to my tanks, and usually around large swords that tend to "ride up" in the gravel. The water current, fish activity (like your BN) all "pull" the plants and if the plant is recent the root system has not yet anchored it, so a good 3-4 inches helps.
After not many months, if you can see the underside of the 29g on its stand (my metal stands are frame so I can get down and look up under) you will find the roots of those two swords all through the substrate on the bottom glass. Echinodorus really have very extensive root systems. When I moved those in my former 90g into the 115g last July, they had been in the 90g for 8-9 months, and a couple of them had roots half way across the tank lengthwise and completely front to back--chunks of bogwood came up on top of the mass of roots from a foot or more away from the plant crown.. If you pull them up and trim the roots periodically, it will keep them compact and may be smaller. I've never done this myself, although when or if I move them I do frequently pull off some roots, but not as a regular pruning activity.
