By saying kissing fish do you mean Kissing Gourami? If the answer is yes, these fish are omnivore and in our home tank it will accept commercial food such as flakes, pellets and frozen food but if they will get their chance they will be happy to hunt and eat fry.
Kissing fish or kissing gourami, typically eat benthic algae and aquatic plants, they will also eat insects taken from water's surface. Kissing fish also filter plankton from the water and scrape the algae from stones. Cooked lettuce is a good alternative for kissing fish kept in an aquarium and any kind of live food.
