I would get a pair of 36" fixtures
each with T5HO 2x39 watt bulb.
that pink bulb enhances colors.
you can get a square acrylic bar to
hold them both up from the center,
and get rid of the glass canopy, as
these fixtures come with wire-legs.
a pair of 1x96w 36" fixtures would
also work, but it's hard to find one
without a half Blue bulb. Blue bulbs
are less helpful with planted tanks.
these fixtures are narrow enough
that you could double up on them
later should you want to get into
more high light demanding plants.
