Can't tell anything from the pictures.
Is there any chance you can post a video of the fish
You can upload videos to YouTube, then copy & paste the link here.
If you use a mobile phone to film the fish, hold the phone horizontally (landscape mode) so the footage fills the entire screen and doesn't have black bars on either end.

If you can post a picture from above the fish, we might be able to see the scales sticking out if it is pine coning.

How often do you do water changes and how much do you change?
Do you gravel clean the substrate when you do a water change?
Do you dechlorinate the new water before adding it to the tank?

What is the ammonia, nitrite, nitrate and pH of the water?
