Lets just say my first betta went into a 5 gallon heated filtered tank and for the next eight years I've been arguing with Walmart employees :P My PetCos and PetsMarts are great and have very knowlegable staff...I'm lucky :)
I learned that little girls are, under any circumstances, allowed to buy more than one betta at a time for fear of them living in the same tank no matter how many times that little girl tells the clerk "I HAVE SEPARATE TANKS NOW SHUT UP ALREADY!"
I learned that bettas -LIKE- to live in dirty water, and that bettas hate filtered water and never use filters, even if you ajust the flow and they are buffeted. I also learned that bettas were made by mother nature to live in puddles. *headdesk, headdesk*
When i bought my first betta the guy at the pet store never told me i needed a heater so when i ask him why my betta is lathargic,pale and not eating he tells me to pour in boiled water from the kettle he is the reason for my first bettas death
Dont you think that if you own a pet store you should tell your customer about the pet that they are buying
I learned that bettas don't need anything bigger that a vase, that vase can be changed once a month and to feed twice a week. They don't need a heater and to never use aquarium salt because Bettafix will fix everything.
