Is It Normal For A Female Molly To Be This Aggressive Every Day All Day?

Hey guys! I've never had sailfin Molly's before any advice would be appreciated. I have 3 sailfin Molly's in there (midnight which is the all black one and only male, kiwI is the orange one, the gray/black one is Ashe..I have ghost shrimp, and a bristle nose pleco full grown just about.

By chance do you guys know why my one female molly is being so aggressive(gray/black female)? She even bullys the Male, I know it's not a hierarchy thing because I've had them for probably a month now, but I'm not sure if I should move the aggressive one into the big tank I have (33g) or what the issue is. This is my second time feeding them today and shes literally biting at my orange molly. She stressed out my Male so bad the other day that he jumped up and got stuck between the lid and heater. Luckily I noticed I couldn't find him anywhere in tank and he plopped down when I took off the lid and the ash one immediately started attacking him again. They might both be pregnant, but no babies yet. Shes mainly harassing my other female (orange one -kiwi)
Is this normal? Would it be wise to move the aggressive one? A little.worried only for.the fact that all the fish I have in my 33g are smaller than her and she already nips at my pleco which is bigger than her




Added music for more dramatic effect LOL

This is every day all day that shes being aggressive, share your knowledggeeee ;D

 

I had a molly that was the same way, female but not a sailfin. Can I ask what size is the tank that theyre in now? Sailfins get pretty big and with 3 of them in there I can almost guarantee that it's because the tank is too small, they don't have enough room to have their own space. I would try moving her to the 30gal and see how that goes. Do u have plants in ur bigger tank? If not u might want to get some so there's more hiding spots. If shes still a jerk then maybe rehome her. Its not worth the other fishes lives.

Thank you for your response! Sailfin Molly's are the Biggest natural species I believe. No other molly or platy they had is bigger. They're in a 10 gallon right now. I'm going to try and move the aggressive one to the 33g and hope for the best. I have a bumblebee catfish in there which is tiny and also a golden dojo loach baby so I'm hoping she doesn't nip at them or idk. I'll try and take her back to the store I guess lol

This is my 33g tank

 

Let us know how it goes!

 

So they were a acting that aggressive due to tank space so I moved them from my 10 gallon to my 33 gallon and all is well, majority of the aggression is gone and they are happy
