It might just be that they were new frags. Some times they can be slow to take off. I recall an article on how small coral devote their energy to securely attaching themselves. Mid size one spend it growing and larg coral use it to spawn. If they were new cuttings they might just be trying to build a strong base rather then get larger. Your tank looks fine. I wouldn't go crazy because of two frags.
