I also got some blue hornets and some pink stardust ladies and they have not opened up yet. Luckily for me they have not melted away yet.
I did put them in a higher flow area in my frag tank to help encourage them to open up.
ReeferMadness512, blindside, and clamgal: Did you have yours in a high flow area?
Other than the flow, I could not find anything else that could help encourage them to open up. So, I am going to be patient.
But I would be open to some more advice. 
I am keeping my fingers crossed that one polyp of each survive.
