Walmart's main objective is selling money, and sadly that shows in the way they care for fish. I was reading a reddit AMA of a Walmart pet supplies & fish area that once worked at an actual pet store had good knowledge of fish.
Here are some of the more disturbing things he said...
-There was a shipment of fish, he was not working at the time. They brought the fish in, just let them sit in a cart in their bags for 8 hours. All the fish died.
-The water reeks of ammonia and fish are often kept at the wrong temps.
-The managers told him not feed the betta (!!)
I was very upset by this and I think Walmart and other non-pet stores selling pets just does not make sense. They need people trained about fish care (and other pet care). Have you experienced stores/companies selling fish that are not pet stores? What was your experience?
