All my bettas are dead or are dyeing

[gingerbread27]

I have lost all but three of my bettas and 2 of them are very sick with strange illnesses that show up over night.. I had a pair of opaque crowntails that died for no reason I know of, then another one swoll up and died I had holes in them flesh falling off I am not sure what is going on. I have never seen anything like it. i just want to give up.

awww,don't give up
There's been a lot of this going around lately. It sounds like an internal bacterial infection. Did you notice white poo?
