New here but I come with a story.
Tonight I went to Wal*mart to see if they had anything I could give my betta to treat him for velvet and while there had a look at the fish. In one of the tanks there were some cute mollies swimming around with a few plecos. Well one of the mollies had died and a pleco was sucking on it. I politely flagged down a worker and let him know there was a dead fish, he looked at the tank a bit with a blank look on his face before spotting the fish and proceeded to lift the hood. Like any normal person I thought he was going to grab a net or something and fish it out but nope he looked at it again before turning to me and saying "Yep, that's dead" and walking away. I continued my shopping and returned again ten minutes later and the poor thing was still there, needless to say I am appalled.
