In my 10G shrimp tank, I use a small in-tank filter (the one that came with the 10G starter set). To keep baby shrimp out of it I buried the filter in a pile of Aquarium gravel behind an ornament. It makes a nice small waterfall, keeps the babies out and I can hardly even see it. If I blacked out the back of the tank it would certainly be invisible.
