5 male guppies 1 female

Hello, so I was doing only male guppies in my 20 gallon, until I saw this beautiful male guppy at the store, the only problem is that I had to buy the pair, and the female seems pregnant. Now there are 5 male guppies harassing the pregnant female, I don't want to stress her out so I need some ideas.
I don't have another tank to put her.
Should I build like a little cage inside the tank or something?
Do you think she will be ok?
Any help will be greatly appreciated, thank you in advance.

 

The general rule is 3 females to one male. Unfortunately, she will continue to be heavily harassed as the 5 males all will want to breed with her, and she will be very stressed and could even obtain fin damage from nipping/chasing. If you're able to somehow separate her that would be best

 

Yea she needs separated. A breeder box or something similar will work short term but you will need to figure out something long term.

 

I was just thinking, if the tank is 20 gallons I'm pretty sure there are separators with perforated holes that you may be able to use in the short term?

 

I agree with David and Laura. This little girl will be pestered to actual death by that many males. Personally if someone told me I had to buy both fish I would have just let them keep both of them but then I don't know how badly you wanted the male. They were condemning this little girl to a very short stressful life. Did you tell them she was going into a tank that would have 5 males in it?

 

This is what I ended up doing, I separated the female from the rest. Thank you all guys! Great advice!

 

Females are larger than males, so one female can do just fine with one male. You don't need multiple females for each male. If there's any nipping, it's the male that gets the worst end of the deal. The problem occurs when a female is outnumbered, as in your situation. She can do fine with one male, but can't hold her own when a mob of males gang up on her.

Yours is a good solution. However, you need to think forward a month. What are you going to do with the female when she drops 30 to 50 fry? Then look forward two months. She'll drop again whether or not she's been hit again. If you don't plan it out you'll end up severely overcrowded.

Time for more tanks!
