My Betta showed up like this yesterday evening, it was ok in the morning. I know he’s been swimming more than usual around a couple of volcanic rocks that have always been there, it’s the only thing in the tank that has rough edges.
The last picture is for comparison (two days ago).
It’s pretty evident the fin is damaged and the red line wasn’t there before the damage.
How much should I worry about this? What should I do?
