For the freshwater benthic (i.e. bottom-dwelling) species, a 10gal aquarium is plenty big. Set up with mature aquarium water and a mature sponge filter. Add lots of a fast growing plant such as Java Moss, Najas Grass or Hornwort and add some full-spectrum lighting to promote the plant growth. You can feed them freshwater live phytoplankton or a yeast-based rotifer food without problem. Infusoria is a good substitute also. Perform monthly water changes, but no more than 40% at a time. When you see a cloud of nauplii in the water (usually around a month) you can begin harvesting. Just siphon water from the cloud and add directly to the fry tank. For the larger adults, you can net them out with a fine Brine Shrimp net or plankton sieve.
