I made my own brine shrimp hatchery kits - - use a 2 liter soda bottle and an aerator with airline and airstone and you are good to go. I find the little ceramic pots from a craft store hold it upright perfectly.

For adults...the basic guideline is
* a 2 foot tank minimum for one adult, 1 foot extra for each adult (always buy tanks for the adult size)
* diet of worms - bait store bought earthworms mixed with frozen bloodworms as a treat
* temperature - keep it below 70*F
* Keep up with water changes
