How long for Kribensis to spawn

[Nalisari]

My Kribensis lost their first spawn to a hungry ropefish. Have since removed them from the community tank to their own private accomodations, any guess on how long before they will spawn again? (The eggs were eaten the first day they were laid if that helps with the time frame.)

I think about every 3 weeks or so. You can sometimes get them to spawn by doing ~75% water change and adding water that is a few degrees cooler when you fill the tank back up.
