Cool! Shrimp are shy but when they figure out you will feed them they will come out at feeding time. I use a turkey baster to feed all my Fish & Shrimp, when everyone sees the turkey baster they come running out. I use the baster so I can slowly feed frozen food and not have alot of waste.
One note Toothie, I wouldn't add any other live creatures to the tank for several weeks, it needs to cycle. Keep an eye on amonia, nitrites and nitrates. Use a simple test strip kit and if amonia & nitrites get to high do water changes.
