If you can, separate the males and females and condition them for about two weeks or so. Choose a heavily gravid female and two or three active males and place them into a tank with lots of spawning substrate like floating plants with dense root systems or artificial substrates. If everything is right, spawning will occur very early in the morning a couple of hours before daybreak. Immediately after spawning, you must remove all the breeders, otherwise, they will feast on the eggs and leave you with almost nothing. Or, you can transfer the laden substrates to another tank or aquarium and wait for the eggs to hatch in 2-3 days. In the community pond that you have, you may be lucky enough to see some eggs on the substrates that you can transfer. Check on this very early in the morning especially if you hear some fish splashing. Good luck.
