Nice blastos, they are one of my favorites.
That's not a flavia (I don't think that's even a type of coral), that's a fungia (plate coral). The plate coral will need to be hand fed a couple times a week. I've never had any luck keeping them for some reason, I've had three and they've all died on me within a few weeks. They can be pretty tough to keep alive.
Are you aware that the hawkfish is not reefsafe? It will eat snails, crabs and shrimp.
And are you also aware that the sun polyps are not photosynthetic, so they need to be placed in the shade and that they need to be hand fed daily (each polyp) because they can't get their food from anywhere else? They are probably the most demanding coral out there, not a good choice :(. Freak had sun polyps before, he can probably help you out with them some more if you want.
