Gourami are unsuitable for the general hobbyist. Generally regarded as peaceful, gouramis are still capable of harassing or killing smaller or long-finned fish. Depending on the species, adult and juvenile males have been known to spar with one another. Aggression can also occur as a result of overcrowding. Gouramis have been housed with many species, such as danios, mollies, silver dollars, Neon tetras, and plecostomus catfish. Compatibility depends on the species of gourami and the fish it is housed with. Some species (e.g. "Macropodus" or "Belontia") are highly aggressive or predatory and may harass or kill smaller or less aggressive fish;
Kissing gourami By increasing the angle of opening of the jaw, this joint allows kissing gourami to access to these nutrients. "H. temminkii", however, is the only species known that uses this articulation in this way. The intramandibular joint divides the jaw into two independent elements so that it increases the degrees of freedom and the potential number of ways of getting food. This articulation, although its mechanism and anatomy are still being studied in a hurry, results in an adaptation of Helodoma temminkii and its feeding. Shallow, slow-moving, and thickly vegetated backwaters are the kissing gourami's natural habitat. They are midwater
