should fountain pens be stored with
the tip up between uses?

No. The ink dries in the feed and slowly clogs the pen. It is better to
store fountain pens in a horizontal position or with the nib down.

I should perhaps add that certain pens seem to tolerate being stored
with the nib up, notably the old Sheaffer school pens.
