Help Selecting fish for my 80L Tank

Great, just make the cory shoal 6 or more (up to 9). Keep us updated!

Agree, you want more cory, it is frankly essential or they can be very lonely--this is a highly social family of fish (whatever the species, the more cories the better). The hengeli rasbora (species is Trigonostigma hengeli) is fine, and a lovely fish, and well matched with any species of peaceful gourami. You also want floating plants, substantial ones, like Water Sprite, Water Lettuce, or Frogbit [as opposed to duckweed]. Some stem plants grow well left floating and also work. Important for shade (the rasboras will really shine) and providing roots for gourami to browse for microscopic food...might even build a bubblenest!
