Just posted on this forum for the first time tonight so I'm new, but I've been lurking and reading for days. I wanted to chime in and say that I work at a chain pet store and genuinely do care about the fish (otherwise I wouldn't be here, right?!). I can't tell you how many sales I've refused because water conditions weren't right or fish compatibility wasn't being considered, etc. Especially with bettas. Don't even get me started on them. They are one of my favorites and they are treated the worst ...
And not all of us are about upselling, either. I am very do-it-yourself-y and instead of selling 50 different chemicals to put in the tanks I often suggest things like adding driftwood to slightly alter PH or plants to help with chemistry. There have been times when people have had 10 items in their hands and have asked me what order to use them or HOW to use them and I've just told them to put it all back and use this ONE item instead. I don't trust most people to handle all this "complicated" chemistry stuff. I'd rather see them take things slowly and get it right than to just throw everything we've got at the problem and end up destroying the entire tank. Of course, I never let my manager hear me during those times! -lol-
Almost every single person I work with has surprised me with their fish knowledge and empathy. We're not all bad! You just have to find the good ones, which can be tough I know.
