Male Kribensis being aggressive to female

[Murf.]

I got a pair of kribs at the end of August. Only fish in the tank. They have been fine together all this time.
Very colorful with the bright purple bellies.
They are always swimming around together and doing the wiggley dance.
I couldn't find the female today. Then I saw her hiding at the top of tank tank behind filter motor. It doesn't matter where she hides, the male is chasing her when he finds her and picks on her. Her colors are faded now. His belly is still purple, but not like it was.
What's up with that?
Will he kill her?
Thoughts?

Thanks

At the risk of teaching you how to suck eggs, are you certain you have a male and a female?

When I kept a pair of Kribs, they did fall out occasionally, which is why I was surprised when they suddenly had a sheet of eggs.

I posted this picture on this forum and asked if they were male and female and got back the answer Yes.https://www.fishforums.net/attachments/img_20210830_112445757-jpg.142536/
The female is shorter and fins are different than the males.
