Down here the preferred habitat is thick vegetation very close to shore in calm water. I sometimes find them in grasses, but submerged floaters like Cabomba and Anacharis seem to be preferred. Also try scooping the net along the bottom right at the water's edge. The best places to look are drainage ditches (if not ephemeral). I think this is because they are such a favorite food of any fish, so you're more likely to find them in water not inhabited by large predators.
On a related note, I haven't had any great success keeping these with anything larger than a guppy (Gambusia affinis, Heterandria formosa, Lucania goodei, Trinectes maculatus have worked out). Even small and seemingly peaceful fish like Enneacanthus gloriosus and Fundulus chrysotus will devour shrimp, even breaking apart ones too large to swallow.
Vegetation is not required for keeping these in an aquarium. I think in the wild it serves as cover from predators more than anything. They are omnivorous and in my experience will do just fine on a diet of fish poop.

Two thoughts immediately came to mind...
These are not peaceful fish if your name is "food" they are quick and hearty eaters...
I have seen plenty of Etheostoma (that's right cute little darters), that had no hope of fitting hte shrimp in their mouth, stalk, chase, and (in an aquarium, literally) "corner" a grass shrimp and tear them apart...
Which then brings me right back to the first thought (modified)... no fish is peaceful if your name is "food"

However, I was unaware that the US had any freshwater macrobrachiums in their waters. Are they native to the US?
