Sparkling Gouramis Breeding Again - Similar to Betta Breeding - Eggs Didn’t Hatch

This is sparkling pygmy gouramis breeding. If you’re new to this channel, you can check out the video where the eggs have successfully hatched

I’ve tried everything to prevent these guys from breeding. The tank’s turnover rate is very high with a very strong current. There are no floating plants. I’ve done very big water changes each week to keep the PH above neutral. Somehow the pair, the same pair(I’m pretty sure), managed to find one spot in the tank that didn't have any flow - under the driftwood. Capturing these guys breeding was luck. The video quality isn't that great b/c I shot it in auto. I didn’t have time to fiddle with the camera settings b/c the breeding happened very fast.
