Strange behavior coming from GBR

[Jleungrx89]

Hey guys I have a healthy looking make GBR that is particular fond of my intake sponge. I’ve had him for about 2 months and recently I would say about 80% of the time he stares at it like he’s praying at it or very curious about it. Every so often he takes a peck at it. Any fish that swims near it, he chases them away. He eats regularly and he’s the only GBR in the community. Is this breeding behavior?

I would say it needs a mate or a few others to keep it busy. I have 10 in a tank now and they are a very social fish.

Have you seen him pecking at it? Maybe he's eating stuff off it?

GBR in my experience tend to claim something in the tank as theirs and chase anyone else away.

My biggest Male had claimed an indent in a piece of driftwood as His home and He only let's the female GBR he paired with come near it(also my angelfish for some reason lol) but any other fish he will chase away.

Seems like normal GBR behaviour to me
