Making a fish tank

I'm a reasonably decent woodworker and was thinking about making my own
aquarium--maybe 200 gallons or so.

Does anyone know a source of information, plans or specs for materials?

I'm not an engineer and would need to know things like how long and wide a
piece of glass or Plexiglas I could use and how thick it needs to be.

Anybody done anything like this?

I was also thinking about the prospect of having only one side out of glass
and the bottom and three sides made out of plywood lined with Formica. Does
that make any sense to anyone out there?

These are things I think about while sitting by my pond with a glass of
wine. It does stimulate creativity!! ;-)

Thanks,
