what i would do, get a divider if your using a 10gallon, and just place one on either side and let them look at each other, but make sure to include a cave or plants or something for the female to run to if she doesnt constantly wanna be hawk eyed by your male.
If your using a 5g or smaller, although i think for breeding you should really invest in a 10g, you can still use a 10g divider, if you cut it to fit, or bend it and clip it in.
if your forced to do this, chances are you wont be able to get the divider clear in the center, but thats ok, my advice is to give the female the bigger side, more room to hide and ignore the male, so your not Literally forcing them to stare at each other 100% of the time. let them be like this for ATLEAST a week, or if your like me and your breeding tank is right next to your bed and you watch it for about 75% of your day, every day.... you'll be able to tell from many signs that the female is not only physicially ready for the male (Meaning stripes, and a bloated tummy full of eggs) But, conditioned enough to where their not always just flaring at each other, but kind of dancing for each other, and displaying a less violent attitude... but i spend too much time looking at my fish, not everyone is so lucky. lol
