Blood Parrot Being Over Aggressive

Hi! So my blood parrot captain has been making a large nest that takes up nearly 1/4 of the tank and has been getting more and more aggressive. He doesn’t really have the ability to actually hurt them but I feel he is stressing them out. How long should his nest last? He is mostly pickin on the Oscar who likes to hang out in the spot Captain (the blood parrot) is nesting.
Thanks

 

Can you post a pic of the full setup? That way we can see what kind of territories there are. Also, what size is the tank and what other fish are there?

 

Hi! I am no longer at my house so I can not get a pic of the full tank at the moment. In terms of the other questions, this is the full stocking:
- 3 lace catfish (Synodontis Catfish)
- 2 pictus catfish
- 1 blood parrot
- 1 (soon to be 2) oscar (s)
- 1 kissing goramie
- 1 bristle nose pleco
- 1 common pleco (not super big yet)

The aquariums is 130 gallons with a 40 gallon sump.

 

How are things going currently?

 

Things have been going better. I re-scaped the tank and they have been doing better.
