haha i dont know the first thing about care for an efflo, i've kept mostly zoas with a few sps so far. i've had it on the top of my rocks for a few months now and it seems to be happy to me. from what you can see in the pic does it look healthy? it gets good flow and i do target feed it with selcon, coral frenzy, and zooplankton. does anyone have a pic of a big colony?
