A Gourami is a sort of fish that lives in fresh water.
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.
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.
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
Perciformes
tropical flakes!
The Kissing gourami (Helostoma temminckii) is of a completely different species from the Opaline gourami (Trichogaster trichopterus). They are totally unrelated. The Opaline is the same species as the 'Three spot, Blue, Gold, Platinum they are all colour sports and these can be bred together. However the cross you have mentioned can not happen. The name Gourami is a name that has commonly been applied to many fish of many unrelated species and in general means a fish that has a labyrinthine system for breathing.
I do not know if your Golden Gourami has a disease or not. Maybe if you explained why you think it may have one and describe the symptoms I could help.
