A pet shop employee told me a lady came in and bought all their bettas, and told
him she was putting them + 50 more in Christmas decorating ornament balls.
First, that's a heck of a lot of feedings & water changes, which I doubt she'll even do.
Second, the remaining ones who don't die will no doubt be sent home with unsuspecting & probably annoyed guests that will flush, release into the wild, or stick in a freezing bowl. Maybe 10% will receive proper care...I'm not a fan of giving animals as gifts/favors for ANY time of year (unless they specifically ask for one), but the winter season in particular is hectic enough.... without adding another responsibility.
I'm not mad at the employee, she'd no doubt be fired for not selling to her & we all gotta make a living.
