I think it depends on the walmart, just got a siphon from mine and they had some beautiful bettas in great shape--better than the petsmart's.
I might have to try getting my next betta from them (if I can't afford an Aquabid beauty).
*shrugs* Must be because the walmart's like 90% staffed by college kids from the nearby campus.
I know not all Walmarts are bad, it just seems like the one in my home town and the one near my college is. I'm just unlucky enough to live by all the BAD Walmarts. I've been to some good ones, but they all seem to be in bigger cities or nowhere near me
And well.... this tank on the website doesn't help to improve their image any
