Article in English: For most gourami pairs, select a tank that can hold 10–20 gallons (40–80 liters) of water up to a six inches (15 cm) water level. This relatively small size and shallow water level actually encourages breeding and fry health, but it is not suitable for all species. Here are a few notable exceptions:  Kissing gourami will only spawn in a large tank, at least 24 inches (60 cm) deep and at least 36 inches (91 cm) long.  Pearl gourami can be bred in a tank with this water depth, but the tank should be at least 31 inches (80 cm) long.  Blue, or three-spot, gourami can be bred in this tank size, but a somewhat larger tank will work as well. A larger tank may minimize stress and injury to the female. Species that grow more than 10 inches (25 cm) long, including the true gourami and giant gourami, may require much larger tanks. Consult an expert before attempting to breed these species, with the exception of the kissing gourami described above. Start by adding a thin layer of gravel at the bottom. Use this to anchor several plants, large enough for the female to hide behind if the male becomes aggressive. Leave some open area as well.  Upturned clay pots and other common aquarium additions can also be added to create hiding spots. If putting rocks in the tank, be sure these are bought from an aquarium store, as rocks gathered in lakes and rivers may alter the pH of the water. Some species, such as the pearl gourami, create a "bubble nest" for the eggs on the underside of a floating plant. You may use actual floating plants, or cut a Styrofoam cup in half lengthwise and float it on the surface of the water. For species that do not build bubble nests, such as kissing gourami, you may wish to float a piece of lettuce instead, which will provide nutrients for the newly hatched fry. Do not cover more than 1/3 of the water surface, as gouramis need to take oxygen directly from the air as well as the water. Protect the air above the water level from cold drafts by attaching a lid to the aquarium. Make sure there is air...
