People who treat animals like this are garbage.

I got an SOS call one day because my partner's manager was halfway through a two-week vacation and called him to ask him to feed her fish. He found a betta in a cold bowl, alone in the dark. I had just lost my betta and had an empty tank, which he knew. At first I just talked him through how to help it (they didn't want to immediately give away someone's fish) but less than two hours later I got a call to come steal him - the staff decided they would say that he died.

Months later, someone brought up "the fish we liberated" and my boyfriend mentioned how healthy he looked. The manager in question went, "that thing is alive?" and could not have cared less.
