Can't say I'd bother calling the higher ups, but there is definitely a way to go about it and that (rude) was not it. You have to win hearts and minds, and even then, some people just don't care. I was listening to an idiot today asking how his new betta would fare against his new demasonis (both bagged up courtesy of petco.) I doubt the guy was even worried about water parameters, ph and whatnot. He would probably not keep an aquarium for more than a few weeks, and thats not a loss to the hobby. A doofus I work with just stocked his new 10g with "a bunch of fish." When asked what kind, he responded with "dude, I got blue, red, green..." I'll spare you the rest. He was also curious to know when the cloudiness would clear up. I tried to explain, but as soon as it got the slightest bit technical, he was on to wanting to see them fight. The best spoken reasoning will not affect these people, nor the cruelest verbal abuse. They will tire of torturing fish sooner than later, moving on to kittens or whatever comes next. Dealing with them sucks, but dropping down to their level doesn't improve things either. Prevention would probably work best, but labeling bettas as "siamese fighters" or labeling an aquarium system with 2 orandas in a 1 gallon only perpetuates it. Too bad companies (not all of them mind you) don't care what happens with the tank after its sold. Whether it houses appropriate fish for years or goes in the trash two weeks later, thats $xx.xx in the bank to them.
