I'm really worried about my new male betta, Flash. A year ago, my male betta, Diamond died, and so I got Flash. Well, before Diamond died, he wasnt active, he was just lying there on the gravel, and he wasnt eating. It's wednesday now, and i got Flash on sunday. Well, when i transferred him into the tank the first 2 days, he was fighting with his reflection or something. Well on the back of the tank, there's a background of the sea reefs. Well he was looking at that, and he was "fighting" it. well today he stoped, and he just lies there, but he still eats.I'm so worried. I don't want him to die.
