Community [General] types almost always require a medium to large group of fish of similar species to be happy. Community fish may become overly stressed if not provided an adequate number of compatible tank-mates.
The thick-lipped gourami has again become common in the aquarium hobby in recent years due to selective breeding which has produced a new color type.(~1985) The new color type, often called a sunset, peach or orange gourami is actually quite pretty.
The wild-type Thick-Lipped gourami somewhat resembles a poorly colored Dwarf Gourami.
Care Information:
This fish doesn't reach a large size, and will be a good inhabitant in most tanks. Often Gourami males will fight amongst themselves, so an eye should be kept on the fish to ensure it does become damaged. A heavily planted aquarium will often ensure that quarrels do not become harmful to the fish.
Most gourami appreciate a planted tank and this one is no different. Thick-lipped gourami will thrive on flake food, though it is a common practice to feed live or frozen food when attempting to breed them.
Whater chemistry is not of great concern as the fish is quite adaptable to multiple water types.
Breeding Information:
These fish are quite easy to breed like most Gourami are...however, raising the fry is always a tricky endeavor.
Females are not as long and also more stout than the males. They also have a rounded dorsal unlike the males very pointed dorsal fin. During breeding time, the males will show a much more vibrant coloration.
Breeding will often occur after a water change. If you intend to raise and breed the fish, you will want a tank dedicated to just these fish. Drain the water so that it is no more than 6" deep. You will want minimal water disturbance, so filtration must not be too powerful. Since these fish breath surface air, plants may prove adequate filtration. In addition, I highly recommend a very well-planted tank, as the fish will create a bubble-nest in the plant material in the tank. Eggs are laid in typical Gourami style, with the male fish wrapping his body around the female's, releasing sperm as the female releases eggs. The male will then catch the eggs in his mouth and place them in the bubble-nest. The male will guard the nest vigorously, and you will want to remove the female to avoid harm befalling her from the protective male.
After 24-48 hours, the eggs will hatch. The fry are extremely small and will require very small food, such as infusoria to survive the first few days. After that, small foods such as microworms and vinegar eels can be fed.
You will want to keep the tank well covered, as the fry require moist air to correctly develop their labyrinth organ that allows them to breath surface air.
This species will cross freely with the Dwarf Gourami, so it is suggested that you make sure not to keep the two species together in a breeding tank.
