If there's no fry in 24 hours just recondition & try again in a week.
First time Dimples spawned was a complete mess because I didn't provide a good foundation for the nest. I didn't want to use styrofoam in the tank so I used the bottom half of a tupperware container, but it was completely unstable. The nest broke apart & dimples got sick of rebuilding, so he ate them all. I think I was using 2 powerful HOB filter too.
I'll be attempting another spawn when Spring arrives. Way too cold to attempt breeding now.
BTW, my spawn tank was 5G super planted messy jungle with a giant piece of driftwood in the middle that occupied half of the tank.
What type of filtration are you using?
