Symptoms and Treatment
How has your betta fish's appearance changed? There's a giant hole/fungis where her head should be.
How has your betta fish's behavior changed? She's completely listless, and won't even eat. Her name means 'pleasantly plump' in German, and she loves food.
When did you start noticing the symptoms? She completely disappeared from feeding times several days ago. I just now found her and scooped her out of the sorority.
Have you started treating your fish? If so, how? I've added more salt and IAL. I don't have any bleach on me at the moment, but I'm going to bleach all of the water buckets.
Does your fish have any history of being ill? No. Sometimes she'd lose a scale from a scuffle. But, didn't seem to mind.
How old is your fish (approximately)?6 months
Slowly, girls have been disappearing from my sorority. Lipstick was the first to go. One day she just stopped showing up for food, then I found her body at the bottom of the tank almost a week later. Then the same thing happened to Bounce. But, I caught bounce and put her in a spare water bucket to monitor her, administer an anti fungal, and try to heal her. Bounce died with similar looking sores on her sides, not the dorsal area.
I eventually put down Bounce after she lost the ability to stay upright and couldn't get up for air.
Mollig stopped appearing for food a few days ago, and I just found her after trying to clean up some algae in the tank. She can still swim for the moment, but is growing weaker. I tried to brush off some of the weird white stuff from her, and a chunk of flesh came off. What in the world is this, and will bleach be enough to kill it before it destroys my tank?
