Using 1/8" Thick Glass (or Acrylic) For A Tank Under A Gallon?

    I have a few pieces of both acrylic and glass laying in my closet from a school project a few years ago. I was wondering if either would be suitable for a small cube (I have enough for a 4" cube in glass, or 6" in acrylic). I know that the usual recommended minimum thickness is 1/4", but since we're talking around a gallon of water, I'm not sure that that'd be required.

    I'm pretty much looking to fill a spot on my new desk. I have a 3 gallon jar I could use, but I'm not big on round tanks, and it's a bit bigger than what I'm looking for.

    I think the 1/4" is preferred to span the longer tank dimensions so it doesny bow. Being only 4" or 6" it should be fine albut fragile.

    Consider also making a eurobrace at the top of the acrylic to add support.

    Not sure I'd use acrylic, as the glass seems to be in slightly better shape.

    Why would I need a eurobrace on such a small tank, anyway? The cube would theoretically beholding less than a gallon, so lets say 0.75 gallons of live weight. Would a brace really help distribute that on such a small cube?

    Acrylic isnt as robust as glass, and it could still bow quite a bit IMO. Better safe than sorry.
