Well, they're not space insects.  Do they live in water?  If so, they have been sold commercially as "Sea Monkeys." They are common brine shrimp.  They do need to eat, though.  I think some powdered food comes with them.  If your tank has a good amount of micro-organisms and algae, they should be quite happy.
