So recently I had a devastation in my tank: one of my Julii Cory’s died, and yesterday my red female Betta died. Today, my other female Betta is just kind of hanging around at the top of the tank. Her and the red one used to swim around together (no aggression what so ever) as if they were best friends lol. Is it possible that she misses her friend and is “heartbroken”. I know it happens with other animals so I thought maybe this was the case with her.
