Question about my Clownhole

[Dearth]

This is my Female Clownhole several times a day she comes to this particular rock and lays exactly like this for anywhere from a few seconds to close to a minute she shows no signs of stress, illness or disease.

She only started doing this behaviour roughly 2 weeks ago so does anybody have an idea or suggestion on what she may be doing? The pair of them are well over 6 years old

My male clownhole is completely normal as are the rest of my fish just my female clownhole is doing this
