Go to the craft store and ask for plastic canvas. It has small holes
to allow water movement and will be easy to cut into any size.

I second that, though I wonder if the holes may be too big, and allow
the young to slip through. There may be a finer mesh variety available.

Anyhow, to the original poster, if you're not familiar with what Andre
is talking about, here are some photos of how I used this craft canvas
to divide a ten gallon tank:

I have seen plastic canvas of different hole sizes. My biggest concern is
the adult fish squeezing between the glass and the plastic if it not a tight
fit. Also, I would soak the plastic in warm water to allow it to expand to
the correct size before cutting. The channel grove frame works great but I
can never find the stuff. One time I used drilled Plexiglas as a divider
and when it warmed up and expanded the tank cracked.
