Thank you all for this info. I have shortened the photoperiod to 8 hours.
The tank is right at 50 degrees now and it has been for quite some time. I
will try the plastic bag thing to darken the tank a bit. I have the
photoperiod skewed so the lights will be on into the evening so I can feed
the fish.

The substrate is fine red flint gravel and I have several good sized limestone
rocks form local streams for hiding places.

Do darters build nests or do they just disperse the eggs? I have some large
redflint gravel. should I add some of this to the tank to create some hiding
places for the fry?

As far as feeding the fry-

How do I make green water? I usually try to avoid algae in my water, so I'm
not sure what I need to do to cultivate it. Any other ideas for small live
food that I might be able to culture on my own?
