HELP!!! an odd Silk Thai behavior

[PufferFreak88]

So I'm not sure whether if my Thai Silk is a male or Female, but lately I've have seen the fish digging up the gravel and its behavior is really aggressive towards any other fishes that get near the gravel that he or she dug up. I was wondering if this is a sign of a female Flowerhorn trying to lay eggs or just a male being territorial? here are some pics.

It built a nest. Usually what the male will do, But by the behaviour its probably a female. Shes trying to breed, Its natural, Means shes healthy. Or its a male being territorial in which case I would separate from the Dats.

That's a bad mix, but from what I know with behavior like that. It is most likely that it is a female behavior.

Right as my male started to mature he started doing this. Yours looks female.
