One of my covid hobbies was setting up old aquariums from the basement. I have a 29 gallon community tank and a 10 gallon shrimp/snail tank.
Tonight as I was turning off the lights I looked over the 10g to see how things looked. I have three red and one black shrimp plus 4 nerite snails (and lots of volunteers that came with the plants). While laughing at a snail stealing the shrimp food, my eye was caught by a flicker of movement. The teensiest wisp of a shrimp. I spotted a few more moving around.
I'm so happy I set up a tank for them without any fish to eat the babies.
