How sad, our beloved betta named Barney died yesterday. My husband went home for lunch and found him floating. I figured he'd die soon though, cuz he was acting funny. He was always right at the surface and he wouldn't eat his food. I guess it's time to go buy another one.
p.s. If you put a kind of mirror in front of bettas, like a shiny butter knife, they puff up like they want to fight because they think it's another fish. It's pretty cool!
