Male gouramis are very territorial. If kept in a smaller tank where they are unable to claim their own territory, they will fight. If both of those gouramis are male (they have a thicker body shape and more pointed, as oppose to rounded, dorsal fins), then it may be necessary to separate them, or move them both to a larger tank.
Put them in separate tanks
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.
yes .they can even breed
Perciformes
im pretty sure they will if the conditions are right

The scientific name for Dwarf Gouramis is Trichogaster lalius.
The "blue" Dwarf Gourami (Colisa lalia) is sexed the same way as all Dwarf gouramis. The male is brightly coloured and the female is much plainer.

Only fish in the same class gourami, and try to keep the fish around the same size as the fish you have.
