Over the weekend, I lost two whites and a blue betta juvenile. One of the whites had its stomach eaten and had no eyes while the other two were totally intact.
On Tuesday when I got into office, I found another red lying dead as well.
I suspect it might have to do with the tubifex worms that have been around for more than a week.
The red CT female doesn't look too good and I hope she doesn't succumb to any illness or bacteria that might be present in the tank.
