Answer
Kissing fish are actually a kind of Gourami, and that "kissing" action you may see them do to each other sometimes is actually where they are trying to get the algae off of each other's lips.
Gouramis are in fact aggressive, and should not be housed with a goldfish for multiple reasons. For one, they may attack the goldfish, especially if the tank is too small. For another, Gouramis are tropical fish that require about ten degrees warmer water than goldfish.
To be safe, you should always keep like with like fish.
Goldfish with goldfish, Semi-aggressives with semi-aggressives, and so on.
