What is wrong with my pygmy corydoras?

I know this is a betta forum, however not my betta is ill, but my pygmies seem to be ill.
I have a 5 gallon tank which I set up at the beginning of September. After a cycle to prevent bad water conditions I ended up with my betta Maximus and first 3 pygmies and then after two weeks I bought two more.
One died right after a day, the rest seemed fine.
Today another one died, which used to be fine in the morning. They have no signs of illness, so I have no clue at all...

I do water changes regularly, the temperature is set at 25°C, I feed flakes that sink to the ground as well, so they can eat this (or is that not enough?) and I also feed frozen food at least once a week. I am just worried that it will harm my betta as well.

That's not really enough information to make any kind of guess. Except maybe you just bought sick fish. Post more info.
Or they coulda been old when you bought them. Like I said, more info.
I'm going to have a mod move this to the appropriate forum.
