She was the fish lady at Petco. I talked to her for a bit when she was bagging the shrimp I bought. She had 12 bettas. My mother was with me, and she asked if it was true that bettas don't need a filter...and the lady said that yes, they don't need filters or heaters, and she keeps all of hers that way. :| Then she pointed out the tank that she keeps most of her bettas in, and it was so tiny. It was probably the smallest tank they sell. I think this is it: http://www.petco.com/product/109885/Petco-Dual-Betta-Bowl.aspx?CoreCat=BettaHPFishTanks It's a shame that someone who probably knows very little about bettas, despite having so many of her own, is in charge of selling them. :-( Just had to rant!
