I have bred them several times and the same method works with all of the Trich Gouramis. First start with a pair. Don't rely on the pet store for help with that. There are tons of materials on the sexing of these fish.
Next once you have the fish condition them to spawn. Conditioning takes a 2-3 week period and involved feeding a lot of live or frozen foods such as blood worms, adult brine shrimp, black worms, ect... The female should be plump in the chest.
Next if possible seperate the two for a few days, they will not remember each other once re-introduced. The spawning tank should not have other fish, it should be filled about 1/2 if using a 10gal-20L. There needs to be object floating on the surface and styro cup cut lengthwise works well, plastic coffee can lid or plants. The male will make a poorly constructed bubble nest under the objects on the surface or next to them. Make sure there are obsticals for the female to escape the males aggression.Place both fish in the tank and over the courase of 3-4 days raise the temp to 84 degrees. Watch for spawning behavior and if you miss it, the males will be violently defending the bubble nest. If you watch closely you will see him picking up and putting very tiny eggs back in the nest. That means it is time for the female to go or get killed.
After the eggs hatch, give it two more days and get dad out of there. The fry will need green water followe dby brine shrimp after they leave the next and are free swimming.
