Seems a Little Fishy
It’s definitely upsetting when you find out that the professionals know less about proper procedures than you, an employee on your first day. But this self-taught fish hobbyist walked into PetCo and was immediately told to scrub all the rocks in the tank, which doesn’t seem too bad… until you learn that could seriously harm the fish.

This person explained to their boss that cleaning the rocks wasn’t a good idea. They even suggested changing the water in a way that would preserve the fish’s health, but it was no use. In defeat, they decided this wasn’t the right place for them to work. It sounds like a wise idea – you don’t want to work with people who don’t know what they’re doing and aren’t open to criticism.
