its my uncles tank, i keep trying to talk him into getting Halides but he is one of those people that confide in everything the LFS tells him because he is friends with the woman who runs it. well their saltwater selection is about 8% so i wouldnt take their word for anything, plus the VERY FIRST fish i put in my tank (after the 2 starter damsels) was an auriga butterfly which i bought from the SAME LFS wiped my whole tank out due to ich. My 125 gallon is STILL running empty to rid itself of the parasite. I will NEVER buy a fish from them again!!
