Why not a different approach: glue a new tank in as before, but fill the
_inner_ tank with water, instead of the outside one? That might not be
*quite* as neat looking, but would still offer lots of unique
possibilities, and eliminate some of the structural challenges people
have brought up. Fish inside, land critters/plants outside (probably not
gerbils or hampsters--these don't take humidity well).

Another possibility: why not have the inner tank only, say, half the
height of the outer tank, and only fill the water to that level. Then you
could add ramps up to this rim and keep amphibians that could climb in
and out of the water. But then the rim would be more visible and
unsightly... You could hide it with plants, maybe?

Cool idea, Tom. ;-)
