frog spawn

I have a couple of different Euphyllias and I seem to get good polyp extension on some but not others, the torches are getting good extension but the frogspawn and hammers do not. Is there a trick to getting this or am I missing something? Tank is a 66g, I have 2 gyre xf 330, I have them set...

Ever since I discovered the frammer coral (mix of frogspawn and hammer), I’ve been wondering how rare are these, how is this coral created, and how many of you have one? Here’s a picture of mine

Looking to buy one of these corals, would prefer bright coloration. Not a fan of hammer corals unless it's an uncommon coloration.
