Are you sure it's a Frogspawn and not a Hammer? Wall Hammer corals exist, but I think Frogspawn only exists as a branching variety.
Euphyllia corals can grow in lots of lighting conditions from moderate light to extremely high light, as long as their acclimated to the lighting.
Flow is a bit more critical though. Moderate flow is great. Blasting it with high flow will cause the heavy tissue to rip itself, on the sharp skeleton.
