Had some Pearl Leeri Gourami's breed without even knowing it. Had them in a heavily planted tank on a bottom rack. The front glass got covered with algae and it wasn't until I cleaned the tank and moved the fish to better quarters that I found six tiny babys.
Male gouramis build a bubble nest in floating vegetation, lure the female underneath and then wrap around her, sqeezing out the eggs, which they then pick up and spit into the bubble nest. If it is in a small tank it might be good idea to reamove the female if possible. A few days or so after the eggs hatch the male is removed also to prevent predation. The fry are supposed to be tiny and need 'green water' and other very tiny micro-organisms for their first foods. One of the books says slowing dropping the water level of the tank down to six inches or so will induce spawning, which suggests they spawn in the dry season in nature.
Since I didn't even realize they had spawned I did - nothing! -, just kept regular feeding of the parents. As soon as I saw the babies they went into a small tank to grow them up and finally a few weeks ago they joined their parents.
Oh, one of the babies has three of the ventral "feelers" on one side!
