Thanks. My sister lost two bettas very quickly before she got Nimbus, who's still plugging along (although with color loss and some fin damage) after a couple of years. And her Rubeus lived to be at least five, and my Benvolio Bashir Betta to a year and a bit. So we're not actually used to having bettas drop dead on us. Most of them have lived more than a year (Albus did, too).
