Give it medium flow and strong light, good alk/calcium and it will grow like crazy. All Euphyllia are very similar and while considered a 'begginer coral', still one of my many favorites. I just recently picked up a 23 head torch for $40
The lower the flow the more it will blow up (typically). They like a lower alternating flow best, IME. While they are a ittle better at taking higher light than other euphyllia, you don't want it to completely blast it like an acro. If the coral was under lower light at your LFS, you'll want to acclimate it. They are fairly easy but they will let you know pretty quick when things aren't right for them.
Congrats, torches have always been a personal favorite !
