Some of these guys that I have in tanks with darker substrates and more wood get very dark speckles and barring.

I know next to nothing about little feeder shrimp. Are they the same as the ones that we get in mass quantities in the salt marsh estuaries here in the Chesapeake Bay? Does anyone know if those could adapt to freshwater conditions?
Don't know about the whole life cycle, but we catch some on S. Georgia on the trips we have been making to the blackwater systems. And one we caught a few weeks ago was in berry then, so apparently they do reproduce in freshwater.

Yep, that's Palaemonetes paludosus.
There is another genus of shrimps that enters our fresh waters, the longarm or river shrimps (Macrobrachium species). These guys are catadromous (there are also estuarine and saltwater species) and get much bigger than Palaemonetes; they are our largest freshwater crustaceans. The commonly farmed 'freshwater prawns' are tropical Macrobrachium species.
One of these days I'd like to get my hands on some M. ohione. They are supposed to have a pretty active and aggressively enforced social heirarchy, kin of like sunfish.

She's dropped her eggs, but I don't see any younguns. Then again, there's darters, quite a few plants, and it's a 55-gallon tank, so I'm not surprised.
