A small one gallon aquarium  (6x6x6in) that includes a small led light.  It is a good way to learn to do nano tanks and/or fish bowls.  This small set up can house a few small shrimp and/or a few small fish with plants, it is a mini bowl.  I include some Caribsea Eco complete substrate ( black in color) and a few small hardy plants that do well in small bowls.  It will makes a great desktop decoration piece, without taking a lot of space.
