My dojo loaches do this all the time. They’re known for it. I have to check their gills or give them a little pet (yes you can pet them).
Edit to add: we also have upside down catfish that just swim upside down all day. Oh, and a synodontis which is a bigger bug eyed fish that chills upside down on the surface plant roots.
