I'm in need of some advise, I'm afraid.
I have owned bettas for a few years and have always prided myself on how pristine their water is kept. I have six bettas now and have never had any issues with disease or temperament. All have been healthy and friendly. However, my newest betta seems to have developed fin rot literally over night. His fins appeared perfectly normal one moment, and then the next they were in tatters. Because he is extremely skittish and tends to dart around his tank whenever something "spooks" him, I thought that he had somehow managed to tear his fin on something, but it only seems to be getting worse. If I post some before and after pictures, might anyone be able to tell me if it is indeed fin rot? I don't want to risk stressing him out further with treatment if he really is just tearing them. But if he is biting them, then what? I really don't know what to do. :c
Additional info: Though I do not use real plants (I can never seem to keep them alive), I use only silk plants other than his leaf hammock, which is plastic.
