I got a half dozen Danios a while back and YT recommended videos on how to breed them.
In likely the jankiest setup ever, we have baby fry! Boy, are they tiny.
Setup: a plastic cake lid, washed and upside down. Layer of lava rock on the bottom. Water sprite as I have no moss. The whole thing just floating in the aquarium. I stressed myself out (and the fish) catching them to put in the cake lid - they're fast! I put four in for two days, then let them back into the aquarium.
I never saw any eggs, and three days later was wondering if they actually laid any. They are the smallest fish I've ever seen.
Now the challenge is to keep the fry alive and healthy long enough to grow to a size they won't get eaten in the aquarium.

Any future attempts at breeding will be with an egg catcher box. It's too stressful trying to catch them in a community tank.
