So I noticed the other day my damsel won't move out of the corner couple days later I noticed it did this in the sand any reason for this

I dont really understand what "this" is. Looks like it has moved out of the corner. What exactly is the question?

 

[POLARBEAR0871]

The two fish you see in the picture stay near that corner and they made like a little indention into the sand like a little hole or something and one of them stay on top of it and the other swims around it they just started this behavior

May be mating behavior?????
