Pregnant Harlequin weird behaviour?

[Tomie]

Hello

I'm not entirely sure if my Harelequin Rosbora is pregnant but for the past week they've been rubbing up against one another then twirling around. I made a post on this earlier in the week. One of my Harlequins is now in one spot over my smaller live plants slightly vibrating and warning off other fish, she also looks to have a slight bump on her stomach. Is she laying eggs? I really haven't a clue whats going on.

can you post a short video of the fish?

Since we’ve turned the light out she’s gone back to schooling with the other harlequins. If she repeats this behaviour tomorrow I’ll post it here.
