Had a weirdo dream that was different enough that I remembered it when I woke up.
It was some dystopian, "after society broke down" type dreas mscape with roving bands plundering for resources, but we still had fish in a bunch of different sized tanks.
The bit I remember was having to do an emergency transfer and submerging a medium sized tank in a giant "could fit a billiard table and a few friends" sized tank, but when we pulled the medium tank out and carried it to the table, it was warping and twisting. Kept thinking it was going to shatter.
