Yep you need a divider like I did for my Red Crown and my Saphire.

Males and females cannot be in the same tank, you're correct. Only for breeding purposes, not for living.
Males can certainly live in a divided tank! I was sceptical for a while and thinking, "oh, if one gets sick then the whole tank is infected" but having a good supply of IAL and salt and other meds is essential to ensure that tank health is kept up.
Some people get colored plastic mesh to make their dividers so the fish cannot see each other. I made mine with clear mesh so they can see each other, with enough plants and space in the water they can guard their side of the wall and go live happily.
Mine have been in their divided tank now for about 2-3 weeks. They still guard and flare but my VT was a boredom tail nipper and since putting him in the divided tank his tail is growing back at an alarming, but welcomed, rate!
And I have never seen such big bubble nests. Dividing a tank lets them be bettas while also keeping them safe. :)

Make sure the tank is at least 10 gallons so they will haveorw than enough space to swim around in. It'd be like almost five each per fish. Don't want to stress the fishes with with a small tank when your using a divider.

The tank is 10 g for mine so they each have like 5g each for their own but yes she's right.

:) finally I got something right

My tank is 5.5g. That's like 2.75 gallons each. Plenty of space. :)

Yes cool it looks great! I have to take more pics of mine with the fish in it. Doing a fish in cycle don;t know how else to do it plus they needed the space and cleaner water with filter and all.

As long as its not filled with a lot of big items then its fine! They need a lot of open space ammand room to go to the top to breathe!

My tank is cycling right now. I plopped my fish in. But I ran it for a few days with their gravel and flower pots from their old tanks. The "slimy" stuff is actually containing beneficial bacteria so I let it establish for a few days. I don't know if it worked chemically but my fish are both extremely healthy.
