My gouramis, and every other fish in my tank for that matter (so I have to throw in a ton) LOVE LOVE LOVE to eat Hikari Tropical's Sinking Carnivore Pellets. They are intended for large carnivorous fish, such as my catfish and botias I have, but they love them anyway. If I don't put enough in for everyone, they will actually fight each other for posession of one. They get really nasty with my Black Skirt Tetras, who like to hog them all. My Moonlight Gourami is also a junkie for Wardley's Tubifex Worm cubes. I feed them those, along with Tetra Min Pro flakes, Tetra Min Variety Wafers, Tetra Min Tropical Tablets, and Wardley Sinking Shrimp Pellets. They seem to go after everything I give them. They are so spoiled. A while ago I bought the frozen "gumdrop" variety pack from Petco, and they loved the vegetable drops they had in there, and liked the Brine Shrimp. Hope this helps. My fish are pigs and will eat just about anything.
