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.

A colour variant of the honey gourami is the red honey gourami, which is slightly redder in colour. When in breeding condition, the male becomes even darker red/orange in colour. The honey gourami is a bubble nest builder that uses plants to help bind together the bubbles. The water level should be reduced to 8 in during spawning, and the temperature should be approximately 28 °C (82 °F) and with a pH of around 7. After
