I agree with Em 100%
99% of all Euphyllia which includes Hammer and Frgospawn require a soft gentle flow pattern to allow the tentacles to gently sway in the "breeze" of current.
I have fragged my Hammer and Frogspawn many times over 6 years and they always prefer medium light and low flow the best!
Now I just have the Frog though as I gave my last chunk of Hammer to my friend's Dave and Tamara for there reef
as I needed to make room for more SPS frags
