hahahaha im sure it would work in most LFS especially some of them were i have a been where you ask them a simple question just to see how knowledgable they are and they get it wrong, honestly it should be manditory to know something about fish to work in a fish store....
in no means do i mean all LFS im just stating in my encounter there are a few out there that newbies have to be careful of, they try and give you some information but most of the time can be completely wrong. I know from experience. Best solution- do your own research and not just from one website or one persons experience, get a couple of sources or opinions
