All gourami belongs to to the suborder Anabantodei and are commonly known as the labyrinthus fishes. Tichogaster trichopterus is " Three spotted Gourami"which has a very good value in ornamental market globally. These gourami are egg layers. They have a peculiar breeding characteristics of building bubble nest for laying eggs. Male gourami usually builds nest and embeds the released eggs(from female) into these bubble nest. Male used to give parental care till the eggs hatch out.
For buiding nest it needs substrate . Almond leaves were choosen because of its high surface area. 3 sets Brooders of desirable qualities (bulges abdomen in female ,well sized male)were selected .These were let to breed in aquarium tank with a breeding ratio of 1:1 in a controlled conditions(temperature:29 C, pH 7.8). Two almond leaves (20 square metres) were put in each tanks.
The nest build by gourami under the leaves provided a greater surface area and stability. The eggs got a higher survivalibilty and the leaves acted as a ph buffer. To conclude almond leaves gives a better breeding result.
