because of my previous post, i have been turning over& inspecting every single piece of live rock, coral & frag, searching for those nudis, so far nothing. now i find this guy & i have no clue where the heck he came from. found him under a frag plug & noticed that once i flipped it over & was exposed to light, he moved towards shade. the stronger the light, the faster he moved towards a shadowy area. i put him in a container, in a dark area of my sump. anyone have a clue? thx!
