The Sunset Thicklip Gourami can grow to an average length of 4 inches (10 cm). They will therefore require a minimum tank of up to 20 gallons for a pair with water of temperature 22-27°C (72-82°F) and a pH range of 6.0-7.5. The Sunset Thicklip Gourami is very peaceful and one of the best Gouramis to keep in a community tank. They get along with other non-aggressive and similarly sized fish species.
