Did Walmart sell live fish?

Walmart is discontinuing the sale of live fish. The world’s largest retailer once sold live fish at an estimated 1,700 stores. But, in a conference call with its suppliers earlier this year, Walmart announced that it would no longer offer fish or aquatic plants.
A freshwater fish could cost you anywhere from $1 to $25, depending on the species.
How do you buy a fish?
Find a reputable store.
Never, ever buy fish from a tank that contains sick fish or fish that have ich (small white spots). Finally, make sure the staff knows what they’re doing. Ask specific questions, such as what the nitrogen cycle is, how big a certain fish will grow and what temperature is ideal for a species.
The majority of common tropical fish live for an average of three to five years, while goldfish are among those living the longest, potentially up to 20 years. Koi, who are cousins of the goldfish, can live up to 40 years.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
Does fish get thirsty?
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems.

Do fish get bored?
Fish-keepers sometimes see their pets ‘glass surfing’ – swimming repeatedly up and down the glass of the tank. This could be the aquatic equivalent of the pacing of a captive tiger that’s bored from a lack of stimulation. But the fish could also be stressed from an overcrowded or unfamiliar tank.
The fish should feel like it’s just come out of the water. Whole Fish should have bright clear eyes and should never be cloudy or glazed over. They should also have healthy deep red gills and the scales should be neat and intact, not partially rubbed off.
