Panda Corydora: Fry Grow-Out Build! 

Some white sand or white color gravel in the bottom tub might work to make fry more visible and avoid the painting step. Another alternative: Some big box stores sell clear containers with white lids that could be put underneath. Good video!

Great video. I hope it works great for you. I am working on a set up similar to yours . For my Panda Corys.

Good idea have you ever checked out master Dean's breeding setup it's close to yours but a little bit different. Looks good
