Main thing is to keep up with the water change regimen, feeding schedule, and ensuring you have good clean water for them to thrive. Smart idea to switch to a sand substrate by the way! Much easier on the discus vs dirt or gravel options. Anyways, continue monitoring and watching their behaviors. Should any turn dark, stay in corners or at the surface, and continue to not eat, then concern will be warranted. Since it's been less than a week, continue to monitor the discus from afar and let them make themselves at home.
I tell my friends that have gotten into discus and fish keeping, that when you have new fish you need to give them some room. It's like being a waiter at a restaurant. It's okay to ensure the guests have plenty of liquids and their food comes out on time and tastes delicious, but no need to hover over the table and creep them out. haha That's my little analogy since one of my buddies is a waiter. haha
Good luck and keep us up to date!
