Just out of curiosity, how big is this QT you're using? You want to be careful with how many fish you add at one time. Being your DT is only a 24G, if you try to put 3 different fish in at one time, you'll most likely crash it. Do you have any other fish in your DT? Based on it's size, you can't have more than 3 or 4 in it in the first place. If these two clowns were your first two fish to put in this tank, why even QT them? Most people here that QT, do it to protect the fish or coral that they already have in their DT. If you've got nothing but LR and inverts in your DT, what disease can you bring in that will affect them? If one of the two clowns did have a disease, they'd infect the QT and one another. So why does it matter? If you had no other fish in your DT, then doing this QT with these two clowns was a waste of time.
