My banggai is missing :(

[mrhasan]

Well today morning, while feeding, I noticed that the female banggai was missing. I checked all the sides of the carpet to see whether it went surfing (although they are not jumpers). Used a tube camera to check some crevices as much as I could reach with it but can't seem to find her

Any idea? The male seems to be eating just fine. The female was also eating yesterday and looked active and healthy.
