i have a really nice lookin female betta that has come down with illness. i moved it from the main tank into a small 10 inch square container. I added some salt and fungus clear medicine (not too much) and i've been changing the water every 2 days in an attempt to keep it clean. it hasnt improved. actually, its gotten significantly worse. the betta hasn't eaten since isolation either. I took a good look at her 5 minutes ago and shes got white spots all over, fungus on her face, and a bit of fin damage (maybe from the fungus?). i think the fungus on her face interferes with her ability to open her mouth. she has a hard time coming to the surface for air. she is active though, at least when i come in the room. I'm thinking I might just have to put her out of her misery. is there a relatively pain-free way to do this? shes gotta be living a pretty miserable existence now. anyone have any ideas on saving my fish?
