Soil with at least 1/2" sand cap, unless you want muddy waters and fluctuating water quality :/
Get a tiny filter, I think cheapest/smallest is the Hagen Elite Mini
@ around $7. Get or find some extra black sponges and glue it to the pre-filter so the shrimps don't get sucked in, also stick some in the output area. The flow is fairly strong.
Not sure about lighting, ppl here recommend the clip on Fluval Mini
(comes with Flora/Ebi kits I think), but I don't think it would fit. If you have a window probably won't need one for low light plants or moss.
