I work at a chain store and get the same responses.
The aquatics department gets about 30 hours a week devoted to it (pretty much just me). In that amount of time we have to feed the fish, take out the dead fish, algae scrub 60 10 gallon tanks twice a week, acclimate and release hundreds of new fish, do over 200 gallons of water changes and gravel vacuuming, cart runs, help customers, open and close the back rooms and all small animals, help out on the register, and make sure the store is 'faced'.
I actually know what I'm doing so I keep the section looking pretty good but it's impossible to keep there from being a few dead fish in the tanks from time to time. Especially when the fish are all in overstocked tanks, have the lights on for 12 hours a day, and most of them have only been in the store for a few weeks. And the tanks are all hooked up into one system, and the medications they give us don't work.
On the flip side:
95% of the people who buy fish don't have a clue what they're doing. I tell every single customer about cycling their tank before putting fish in and maybe 1 out of 10 actually listens to me completely.
If I say you can fit like 4 small fish in that aquarium, they buy 5 medium fish. If I say do 20% water changes weekly, most people do them monthly. Half of the time I tell customers that they're not doing enough water changes they act like I just personally made they're life more difficult. If I say these fish like to be in schools, they buy 2 of each kind.
I can't begin to say how many customers come to me saying they do one large water change every 6 months or so. I tell them that's why there fish keep dying and they just go ahead and buy new one's acting like I don't know what I'm talking about. Alot of people think topping off water from evaporation counts as a water change. Half of the people who come in have never gravel vac'd their tank.
Alot of people buy those small two gallon aquariums for their kids or whatever, and then I get to tell them they can't fit any fish in there besides a betta. Most mothers don't like to hear that and get the fish anyway.
Lmao I get so many dirty looks trying to do the right thing. It feels like arguing with a brick wall and gets very tiring. Most fish owners are just as bad as the corporations. It's really making me question the morality of this hobby.
I guess that would be the counter perspective of the employees who actually know what they're doing and try. Done ranting... for now.
