Gourami- are medium sized fish.
Aquarium Gourami are practically incompatible with other members of their family.
The first reason- labyrinths(Gourami, lyalius) love warm water more than cool water.
Representatives of the families of cichlids and scalar also get along with Gourami.
Gourami- curious creatures,
tenacious and active, also feed, breathe with gills and atmospheric oxygen.
Gourami also destroy parasites(such as hydra and planaria)
that have fallen into the aquarium with feed.
Gourami fish are not viviparous,
that is, they lay eggs, and do not immediately give birth to offspring.
Gourami have the ability to breathe oxygen,
after which they sometimes swim to the surface of the aquarium.
Gourami in these regions are of industrial importance,
but in many aquariums in the world they are ornamental fish.
Adults with Gourami sometimes attack small inhabitants of an aquarium, and
they have to be relegated to larger fish.
Be careful: males with Gourami always defend their territory, entering
into a confrontation with rivals of the same or close form.
The Gourami's nest is large in diameter but not high,
the chatso nest is sloppy built, they can spawn even in a strip of foam.
Labyrinth fish Gourami can live in the aquarium for 4-5 years,
glass catfish- up to 8 years, and piranha, referring to the characteristic haratsinovyh, lives in captivity up to 10 years.
A long time ago, when I started my first aquarium of 35 liters and stuffed a bunch of fish there,
including two marble Gouramies, the latter were like mice,
did not touch anyone and coexisted peacefully in the“little hostel”.
