Pearl gourami for the fish in times of stress. The pearl gourami is a bubble nest builder that uses plants to help bind together the bubbles. The water level should be reduced to 20 cm (8 in) during spawning , and the temperature should be approximately 28 °C (82 °F) and with a pH of around 7. After spawning both adults cannot be kept together. The eggs hatch after two days and the fry become free swimming three days later (Ter Morshuizen 2007).
