Most of the time the equipment in an integrated system leaves a lot to be desired. I have an eclipse 12 that has a bunch or CRS in it and I just put a pre-filter sponge on the filter intake and im good to go.
I would personally get the 20L and get your own light and filter. There great for scaping and also watching the animals inside. If you want shrimp it would be best to keep it shrimp only as I would almost guarantee that a nice new born shrimp would be a tasty snack for a hungry danio.
