Can't agree here - my Mississippi silversides don't fare very well
either!<<
This doesn't seem to hold true in north central Texas either.

It's a possibility.<<
Most of my collecting is done out of the West Fork of the Trinity River NW
of Fort Worth. During average rainfall years, the river is slow at best and
within the Refuge area, has a large number of backwater areas with little or
no current. I have had "better luck", meaning an additional day or two of
survival, when the silversides have come from the backwater areas where
there is little current (none during the past summer's drought even when
water was present). However, regardless of the collection location, I have
had individuals expire within 10 minutes of being in the bucket no matter
how carefully they were handled in the net. I would love to exhibit
silversides in one of our Nature Center tanks but have given up trying until
I learn something new that might give me a fighting chance to keep them
alive. So for the fish's sake, please keep throwing out ideas!
Thanks,
