Above 75F and below 80F is best for all Anabantids.
A Gourami is a sort of fish that lives in fresh water.
A gourami needs the same water as any other tropical fish. Warmish water (21-25 degrees celsius) with a few drops of water conditioner, depending on the size of the tank.
yes .they can even breed
Snakeskin gourami was created in 1910.
Not really. There will be some bullying in the tank if the gourami is bigger than the dwarf gourami. Usually the dwarf will be left lone but there is usually fin nipping.
The building time varies depending on how fast the bubbles burst. This will vary depending on the temperature of the water and the airflow above it. The male Gourami will be constantly repairing his nest throughout the whole time it is in use so broadly speaking the nest will continue to be built until the fry are free swimming.
I would advise not to add a dwarf gourami with a honey dwarf gourami. The honey gourami is very shy and much smaller than the dwarf gourami, and the dwarf gourami is prone to being very agressive. Depending on your luck, you might get a gourami with a nicer temperment. I wouldn't suggest it though.
If you give a bit of information about the tank and the water parameters someone may be able to help you more. All I can do at this stage is say what they need and then you will have to see if that is what yours is getting. A reasonable sized tank (15gals minimum) because Kissing gourami (Helostoma temminicki), although they are air breathing Anabantids also breath with their gills and will grow to about 12" long. Water temperature around 73F to 76F. A cycled filter to keep the water clean and liveable. Regular feeding with some kind of algae rich fish food.
im pretty sure they will if the conditions are right
Put them in separate tanks
No, gouramis are egglayers.
The kissing gourami Helostoma temminicki comes from the far east. It is reported to be found in parts of India and Malaysia
