Is my harlequin rasbora pregnant?

[Tomie]

Hello.

Lately I’ve noticed that my harlequin rasboras have been spending a lot of time vibrating against one another and then twirling. This has been constantly happening for the past 24 hours on and off. I Googled it and it said they could be mating! Also, one of my harlequins looks to have a slight bump of white under its stomach. Could she be pregnant? If so what do I do and how would I go about it. Ideally I wouldn’t want her giving birth in the tank for the other fish to eat the babies. IF this is the case. I’m new to keeping fish and I’m absolutely useless at what to do in certain situations as it’s the unknown.

can you post a picture of the fish with the white bump and a short video of the fish twirling?
