This can be even worse. Gourami, like cichlids, put into a tank soon regard the entire tank as "theirs." This is why it is never advisable to introduce new fish of the same or closely-related species [when dealing with these territorial fish] once a fish has become established. Now, sometimes certain fish behave contrary to the "norm" just as dogs, cats or even people; but you won't know, and it is wisest to assume the norm. Other members have written of single Gourami that have killed any other gourami in the tank, and in a 55g tank.
The larger the tank and the heavier it is planted sometimes lessens this, but a fish that is hounded by a bully will not be healthy, and not only is this cruel to the fish, it is dangerous for everything in the tank. In a large tank (4, 5 or 6 feet in length, well planted) introducing all the gourami at once, it might be workable unless one of the males happened to be abnormally aggressive.
