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.

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.


I didn't know that Plexiglass expands when wet - I'll have to keep that
in mind for a future project. The craft canvas stuff may expand, but
it's so flexible that it isn't an issue.

The Plexiglas was very tight between the front and back glass of aquarium.
The temperate of the water, 27 C, made it warp and expand enough to crack
the tank. I'm sure if the Plexiglas was a bit smaller the aquarium would
not of cracked.
