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.
These are a 'sport' of the Blue or Three spot Gourami (Trichogaster trichopterous) the male will grow to around 5.5inches the female may be an inch longer.
yes .they can even breed
A Gourami is a sort of fish that lives in fresh water.
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
My opaline male & golden female have been interacting as a usual couple for about 8 months since thier introduction & are now finally mating... hopefully they do produce young... I believe they are pretty much the same species genetically apart from the colour, so I should update this when the young ones arrive hehe...
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
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.
