It sounds like some have happy endings, and in those cases, it seems the owners do get the enjoyment of watching the little one fill out into a full fledged betta. I just wish mine had been one of those cases.
But yeah, they don't give any indication at purchase time that "Hey, this baby fish requires a LOT more care than an adult!" I knew that when I got it, so I did at least have eyes half open.
