Nope.  Tanks are routinely sold without any sort of insulation under them.
While I have read of people putting styro or thick cardboard under tanks to
solve any slight unevenness, and I've actually done it a couple of times
with a long tank on a questionable surface like an angle iron stand, it is
certainly not a necessity under most circumstances.  More people than not
level their stand carefully and then place the tank directly on the stand.
I think most tanks (at leat those made in the U.S.) these days tolerate
this treatment without problems.  I also suspect that if YOU happen to be
the person who gets one of the few that DOESN'T handle this treatment, you
are gun shy forever more.<g>

Sort of like I ALWAYS tell people to fill a new tank and check it for leaks
before setting it up.  Only once, out of all the tanks I've been involved
with setting up have I seen one leak, but it was enough of a pain in the
neck that for me it's worth the effort to be extra cautious!
