Here's one: So I walk into one of my LFS's to check out some stuff and I overhear a lady asking a worker/manager if ich is curable.. I laugh and walk away to do my browsing. I come back and overhear the managers advice and frankily was quite shoked. She was using Quickcure ich meds. He was giving her advice that a beginner dealing with ich would have been able to figure out herself... which would never work and end up killing her fish anyways or flatly not be able to cure ich. He told her that dosing 1 drop per gallon and doing daily or not doing water changes at all would work (willynilly with the water changes)... He also told her not to take out her carbon from her filters... Daily water changes while treating for ich doesnt allow the full three treatments max (with Quickcure) that would allow for some buildup of the meds. Treating and not doing water changes at all would build up too much of the meds and kill her fish. Not taking carbon out of her filters would nullify the meds. When I was a beginner I understood the frustration of not knowing what to do, many times ending up with dead fish from overdose or rendering the meds ineffective thus letting the ich take over. So to help her out I gave her my advice. He clearly became quite angry stating that if he got caught giving her that kind of info he would be promptly be pulled aside by his superior and reprimanded. Why? Because if her fish died she would have to spend more money on new fish? I also told her that half doses would be fine to avoid any overdose and to follow a certain schedule of water changes (I have a post on MFK that outlines the technique that WORKS). Is he mad because I was telling her to use less meds so that she would maybe have to come in and buy another bottle sooner? Maybe not because her fish would be dead by then... I don't see why his superior would reprimand him for giving a customer advice that actually works... I think he got offended because his advice was crap and he is supposed to be the expert. Luckily she wanted to hear what I had to say, but it's up to her whose advice she trusts. I hope she didn't listen to his or her fish should be dead soon or already dead. Me and my friends had a good laugh when I told them how this employee, who seemingly knows his stuff most times, gave out crap info, and got all pissy when I told his customer advice contrary to what he told her.
