Blueberry is dead. Finally.
Blueberry may have been the longest-living betta fish in the county for all I know. I searched "betta fish life span" and Google kindly told me "2 y on average (In captivity)" with a picture and everything.
Yeah, Blueberry doubled that estimate. At least. Even after spending her first couple years in a pickle jar after she and her former neighbor fish called bullshit on the "females can be kept in the same tank" myth. Or maybe we just had particularly bitchy fish who missed the sharing lesson in school.
