I put these guys in most of my tanks as general-purpose scavengers and fun
things to me to watch. If the fish residents are small (and/or the shrimp
are large), they can survive a long time, and if not harassed by fish
looking for lunch, will be quite active in the tank, crawling along the
substrate, swimming around, lurking in the plants, watching cable TV, etc.
If the fish residents are larger (and/or the shrimp are small), then over
time the shrimp will likely be picked off as healthy and nutritious lunches.
And I have had these local grass shrimp in with Heters .... Heterandria
formosa, aka "least killies", although since they're not killies I'm pushing
the usage of "least live-bearer" as the preferred common name... for years
with no obvious problems, shrimp-to-fish or vice versa. (In comparison, last
night I watched four 3 cm long Fundulus chrysotus in my "baby killie" tank
build up courage to pick on and finally kill a smaller shrimp in their tank
.. and then like young cats with a mouse, go through an
experimental/learning "okay, apparently it's dead .... can we eat it, or
what? And how do we get in to the good stuff? " phase.)
However ... I assume that the shrimp are highly opportunistic scavengers,
and will take fish eggs or fry when they find them, ... and so I probably
lose some Heter fry to the shrimp, although I have not actually seen that
happen.

It's a fish-eat-shrimp-eat-fish world.
Also a Doug-eat-fish-&-shrimp-world.
Will that be fried or broiled, sir ?
