Taking their life span into account their memory lasts about the same as yours and mine. They learn very quickly, and remember things like hiding places in their environment, who feeds them, what a net does and many other thing that would be necessary for survival in the wild. They are relatively short lived fish so obviously the length of time their memory lasts would also be limited by their lifespan. A fish that learns what a net does never forgets it for the rest of its life.
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.
Put them in separate tanks
yes .they can even breed
Perciformes
im pretty sure they will if the conditions are right
dwarf gouramis live in sluggish backwaters of northern India
i heard that it was around 3 months from somewhere
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.
The scientific name for Dwarf Gouramis is Trichogaster lalius.

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