haha! i don't think anyone actually works in the fish section of my walmart. seriously, you have to get someone who is busy stocking sodas to help you.
BUT, my petco has at least one employee who probably hates me. you cannot believe the misinformation i have heard them spout to people buying bettas. D= it's truly terrible. i sometimes correct them, and it usually has to be in front of the potential betta buyer. i'm not into making people look stupid in front of their customers, but what are you supposed to do when they answer, in response to the question, "how do i take care of it?"
"oh, you just take 'em home, and put 'em in a little bowl of tap water. you can replace about half of the water every few weeks."
i mean, really.
i have an idea though. i am compiling a list of basic betta info. i will make small little flyers, and stick them in all the betta bowls and tanks at the petstores.
that way maybe people will get some useful info, and be able to care for their fish properly. =(
