I tried to do the amputation on the fourth betta but it was too close to the body. He didn't make it 4 hours! Actually I am going to be getting a lie betta again, waiting for the disease and will try to stop it via amputation. I stopped what people said was columnaris on my blue female Marge (except only one other girl had it, and it was ORANGE rather than dark blue clump on the fins) and it worked. She was cheesed but it worked
And I'm glad this baby betta lived :p although I am certain he stalked and killed some of his siblings
survival of the meanest.
