How did you acclimate the corals?
Honestly, after a day it's hard to tell how poorly they are doing. If they are still having issues after a week or so then I would look at potential issues.
I know you didn't ask about the clowns but it might be a good idea to rehome one of them. Once 2 of them pair off they will harass the 3rd to death, especially in a tank that small.
