Gourami are native of South Asia and found in wild in India, Pakistan and Bangladesh.
In South India, the wild catches of gourami are sun dried for use as dry fish as well as for animal feeds. These blue gourami are found among the vegetation in many rivers, streams, ponds and lakes. Blue gourami grows to a length of about 1.5-3 inches.

In wild the male has diagonal alternating stripes of red (orange) and blue whereas the female are more silvery in color. By selective breeding many breed variants of blue gourami have been developed with striking colors and patterns.

Feeding dwarf gourami in fish bowl

You can feed the pets with blood worms, flakes and pellet formula feeds. They also like live bloodworms and tubifex worms.
A varied feed of algal and animal sources can give them balanced amino acids, vitamins and minerals.

Breeding blue dwarf gourami in fish bowl

Apart from color patterns the male has pointed dorsal fin whereas the female has rounded and curved dorsal fin.
Mature male builds bubble nest among the floating vegetation.
Peat fiber also can become a good nest-building material.
When the female is induced by the male, it releases eggs on to the bubbles and male fertilises them.
This may happen several times for about 2-3 hours and finally the male will release bubbles below the eggs to cover them completely.
The female fish must be removed after spawning as male becomes aggressive and guards the nest.
In about 12-24 hours the fry of these will hatch out and continue in the protective bubble nest.

In three days they will be developed sufficiently using the yolk sac and start leaving the bubble nest.
At this juncture the male of these blue dwarf gourami fish must be removed as it may start preying upon the hatchlings.
