Well, in that case, let me proudly say I have had one in a tank since
11-8-97!  :)   I haven't really concentrated much effort on this species,
so I can't comment beyond what I wrote to Casper, which I copy below.  I
haven't looked it up yet, but someone mentioned to me that Trautman, in
Fishes of Ohio, states that this is an annual species, only surviving one
year.  It will be interesting to see how long mine lives..if it's not
before I get home tonight  :)  Guess I'll be doing more regular water
changes from now on!  :)

This was the exchange with Casper:

Around here, I find them in quiet, shallow inlets of medium to large
(Olentangy, Scioto R).  Don't know if they're limited to these habitats.
Perhaps the larger populations can be found nearer to the TN River.

I have one that is in my darter tank, a LONG, shallow tank with a
for current.  Seems like the silverside stays at the quiet end of the
and doesn't travel around much.  Like the darters, it stays in one place
and waits for the current to carry food over it.  Perhaps yours was
attracted to the shallow pool by the large numbers of insect larvae. 
are certainly surface feeders.

I can't confirm that they prefer company.  Whenever I have caught them,
has been one at a time, in different areas.  I kept mine alive by putting
it in a large cooler with water from the river for transport.  Then I put
the fish into a tank with water just the same temp as that in the cooler
and let it warm to room temp over night.  I used a powerhead with a
for aeration.  I use this technique for all wild caught fish when the
is cold.

They are not aggresive feeders in the aquarium.

I have also caught them along the shore of a lake in central Florida.
Can't say what species exactly.  They didn't survive long under the
conditions by which I handled them at the time.
