You all may be saying, "Well, duh!" but I finally figured out what may have been the cause of my bettas getting so sick and dying.
I have been using the same net for all my fish. :rolleyes: When Pinky died, I used the net to get him out of the tank, then I used it on Grapel, and on Glitz. I feel like Typhoid Mary!

Glitz is now lethargic, hanging out at the top of her tank, etc. I'm praying that she doesn't die too.
And I'm buying a new net!!!!!!!!!!
