These are one of the easiest and most interesting fish to breed in an aquarium. Set up a five- to 10-gallon breeding tank and let a plant float on top. (Breeders in Asia use a banana leaf.) The male (except the blue gourami) will begin building a bubble nest beneath the leaf, rising to the surface and exhaling a bubble that sticks to the underside of the leaf. Once enough bubbles have been amassed, the male and female will mate beneath the leaf, the male bending his body around the female’s while she releases eggs. The fertilized eggs float up into the bubble nest.
Once the mating is done, remove the female since it is the male gouramis’s job to protect the nest and the young. Within a couple of days the larvae will become apparent and will eat the yolk sac. After that, move the young to a nursery tank and feed the fry cooked egg pressed through a piece of cheesecloth to make pieces small enough for them to eat.
