Well done!
I use a Turkey Baster for water changes in my shrimp tanks and I'll check the bucket for any shrimps that are sucked up every time I place water in there. I tend to not feed my shrimplets purposefully. I will add leaf litter and alder cones in the tank a soon as I see berried shrimps on top of the ones that are already in the tank. This will allow of leaves time to start degrading and for micro-organisms to grow on for them to feed on. I often worry about over feeding when I attempt to feed the babies along with the adults. The tank itself should already have a decent amount of food for the shrimplets.
