They could just be acting weird or maybe they are pairing up.
Have you vented them?
I'd put a pot or slate in the tank just in case

Looks like spawning behavior to me.

when preparing for spawning, they will dig a small depression in the substrate near a state where they intend to lay eggs, no other fish will be allowed to get near this area and will be nudge, pushed, threatened.

A series of displays where in they enlarge their throats as displays to each other. you might want to check out this link breeding peacock bass detailing my experience breeding them.
