I just got this frag. put it in last night. i saw some hermit crabs on top of them grazing..they didnt open up at all that day. this morning now that the lights are on i can see this Clear Jelly like substance covering the heads..there is one head that is perfectly fine. and was actually the only head that i didnt see get stepped on by the hermits...Is this Zoa Pox...or could it just be there reaction to being "attacked per say" all the other frags i got from NERAC/ReefGee are looking perfect. so im just a little confused.
