Good ideas. I have had luck with brine shrimp nets and have also used a net
to chase fry (or adults) into a clear plastic fish bag with good results -
wide opening and the little devils apparently can't see it (or sense it
with their lateral line system, or whatever.....).

I've done it but with using a small flashlight with a normal, clear lens.
In fact, this technique was extremely useful about two weeks ago when two
pair of young Bolivian rams spawned simultaneously in opposite corners of a
ten-gallon tank.  I figured that catching the other inhabitants of the tank
would result in total chaos (as if there weren't enough already) but the low
light made it fast and painless.  The other inhabitants included some very
active Notropis species--please, no embarrassing questions about why I was
keeping shiner minnows with Bolivian rams. :-) There was a large rock in the
middle of the tank that seemed effective in keeping the two sets of parents
away from each other, at least until the fry were free-swimming.  Then I
siphoned out one set of fry and removed their parents, again at night.

I didn't know this trick had already been documented.  I came up with it on
my own out of sheer desperation.

I, too, am known for being resourceful/thrifty/cheap this way.

My favorite fry-puller is made from a plastic soft drink bottle.  Cut
off the top just below the level that the bottle becomes cylindrical.  
Punch a hole in the side of the lower piece. Turn the top piece upside
down and push it into the lower piece.  Voila, a mini-minnow trap.

Place it on its side in the tank, baited with something irresistible.
The small hole is to let the air out - there won't be much water 
circulation, so you *must* check the trap every 10-15 minutes.  I caught
86 3-4cm kribensis fry in less than half an hour in a heavily planted 
tank using one of these traps baited with white worms.  You can't beat
the price, either. :-)
