I know I shouldn't do it but I couldn't help myself. When I was in walmart (their the only store that carries these compressed rawhides my dogs love) after picking up the bag of dog treats I went by the fish tanks. I was surprized the goldfish and tropics weren't crowded and the water looked clean and the fish were healthy looking. Then I saw the Betta cups..all the water was cloudy and one fish looked like he was blind*SICK* Then I saw a tiny dead one. What got me was there was fresh food floating in the cup so the staff are still feeding the dead Betta they don't even realize he is gone. Walmart Bettas have to be the most neglected fish on the planet. Sometimes I wish they did not have the labyrinth organ so they would be treated with more respect and given more room. I feel pet stores abuse the fishes air breathing to their advanatge in order to save space.
