First, you will need to get a set up. Don't think aquarium, think shrimp farm. Get 2-6 large rubber made plastic storage boxes, a cheap 6' shop light, gang valves, gravel and airline. Set the boxes up and cycle just like a tank or cheat and use a carbon filter bag. Using only one bulb put the light on top of the boxes and add shrimp to each. If you can affored it get some java moss and break it up between the boxes, it will grow like wild fire. The shrimp will thrive at room temp as long as it is 70 + degrees. Once you sell some shrimp, get sponge filters for each box.
