I'm in a local aquarist group here and I read this about how beneficial
Indian Almond tree leaves are. They help Gouramis and Bettas to build their
bubble nest and that it has this antiseptic properties that also helps in
healing, in acclimatating fish (a big local supplier always use it in the
tanks for the new arrivals), and best of all apparently helps in maintaining
the tank free of fungus which is a mayor problem with egg layers.
Concentration is unknown but usually they add one leave per 10 gallon. Again,
this is what local breeders use with good results.

tank decorations are good for gouramis. Find a style that you like!
Natural is my favorite, but other common themes are beach, artistic,
surreal, fantasy, colorful, Greek or castle ruins etc. With natural, it is
common to have live plants, real or fake driftwood, rocks, and a subdued
gravel from tan to brown to black. Since your dwarf gouramis are very
bright and colorful, I recommend a black gravel. That way it doesn't clash
or hide the colors but really makes them pop. It will do the same for any
other colorful or bright fish in your tank, just not dark colored fish.
For a beach theme you can use fine gravel (sand can be dangerous), flat
non-spiral seashells (disinfect and test pH and kH first) and limited tall
skinny plants with some driftwood with a blue background. You can use
undersea ornaments like treasure chests, ships, etc if you want. Artistic
could include anything you want! A fun idea is glass beads or tiny marbles
for gravel. Fantasy can range from castles and dragons to psychedelic
colors. Building a tank is a lot about reflecting your personality and
what you want it to look like.
My only concern would be that the gouramis may eat your plants. If you
choose to go with live plants, stick to ones with large, broad leaves.
Java fern, swords, and lotus are good candidates.
My gouramis like
anything they can hide in. I recently bought a large castle with many
openings and they are either in or around it all day long.
