Something killing off my sorority?

[Hassled]

In the past two days I have had two females die. I cannot think of anything that it would be, because just the days before they die they are super active and eating normally.

The only symptoms I can give is that right before they do die, their lips get super puffy and their lips lose color. But honestly that is all that I see as far as symptoms go.

The tank has been going well for a month to two months maybe now, so I have no clue what would have happened all of a sudden.

Any ideas?

What size tank? Filtered, heated? Water change schedule, how much water? Tankmates? I had 2 unexplained deaths a couple months ago & never figured out why, so far nobody else has fallen ill or died. I hope you have no further deaths.

It is a 10 gallon heated and filtered. 80 degrees, parameters are good. Fed them hikari betta pellets. Changed the water weekly, it is cycled.

Did more research and I am pretty positive it was Columnaris, and ontop of that they showed almost no signs until it was too late.
