Kissing gouramis (Helostoma temminckii) are commonly known as kissing fish or kissers. Members of this species will sometimes come together and lock lips, hence their name. While they can reach up to 12 inches in the wild, those who live in aquariums rarely measure more than 6 inches. They're semi-aggressive and can become territorial, so they're best kept in a large tank with others of their species.
Feeding Kissing Fish
As omnivores, kissing fish can eat a range of different foods. The bulk of their diet should be made up of a good-quality flake or pellet food with a high vegetable content. To give them broader nutrition, supplement their diet with spirulina algae wafers or vegetables, such as lettuce or watercress, as well as meaty foods, such as blood worms or brine shrimp. Feed them once or twice each day. If you have good algae growth in your tank, these fish will also spend time grazing on the walls.
