In my experience, honey gouramis don't pair up. Any male will mate with any female he can persuade. The first sign of potential spawning is the male swimming in front of a female with his nose pointing upwards. She'll ignore him at first but then gradually starts to get interested and follow him to his bubble nest. After a few days of the female following then turning away, they eventually spawn by the male wrapping his body round the female and turning her upside down. She expels a few eggs and he fertilises them. They will both be in a sort of stupor for a few seconds. The male comes out of it first; he sucks up all the slowly sinking eggs and spits them into his bubble nest. He will chase the female away till he's got them all, then they'll spawn again. Once the male has enough eggs, he will chase any other fish, including the female, that come within a few inches of his nest. But with other fish in the tank, the chances of the eggs surviving to hatch are slim. While the male is chasing one fish, another will spy its chance to sneak in. Even if the eggs do hatch, once the fry become free swimming, they'll soon be eaten.
