Green Terror Trying to Spawn?

[Peetree]

So a week or so ago I posted asking if my GT was male or female. Got mixed responses so unsure where to go from here. Although, GT has just cleared out a spot and is guarding it ferociously, even attacking me when I get down to look st the spot. It is completely on the other side of the tank from it’s old territory. Pics of the spot and GT:

I think it's a male.
What it's doing is part of the breeding cycle. He is making a fry pit. Part of the courtship routine, trying to attract a female with the glorious pit he dug.
My male Sagittae takes it to another level...
