I've been scouring the web for as much information on bettas as I can find, and I've come across several people writing about how they let their bettas nibble on their finger. There is even a video on YouTube of someone putting their tongue in the fishtank and letting the betta bite it!
I was just wondering if anyone on here does anything like that with their betta. Is it harmful to the fish? Does it hurt your finger if he bites? I thought it was sort of interesting that people do that.
