What it is
This small fish reaches a maximum length of 8.8 centimetres. Wild males display diagonal stripes of alternating blue and red, while females are silvery. The dorsal fin shape helps distinguish sex, with males having pointed fins and females possessing rounded ones. Thread-like pelvic fins contain touch-sensitive cells. Captive bred varieties often show solid colours like powder blue or red flame. They can project a short stream of water from their mouths to catch prey above the surface.
Where it lives
The species originates from Pakistan, India and Bangladesh. It lives in slow-moving waters such as rivulets, streams and lakes. These habitats typically feature abundant vegetation. Although native to South Asia, the fish has been widely distributed outside this region through the aquarium trade. It tolerates temperatures around 27 degrees Celsius.
How it lives
Dwarf gouramis are omnivores that prefer a varied diet including algae and meaty foods. They are generally peaceful but can be slightly territorial. In the wild, they use their ability to spit water to hunt insects above the surface. This behaviour helps them access prey that other fish cannot reach. They thrive in community tanks if provided with adequate space and hiding spots among plants.
Breeding and life cycle
Males construct elaborate floating bubble nests using plant material and debris. Spawning requires shallow water levels and warm temperatures near 30 degrees Celsius. The male courts the female by flaring his fins. During spawning, he embraces her to release and fertilise up to 800 eggs. He protects the nest and fry until they are free swimming after three days. Females should be removed post-spawning to prevent aggression.
Fish and people
Historically, this fish served as a popular food source in its native range alongside snakeskin gouramis. Local names include Kholisha in Bangladesh and Kungee in Punjab. Today, it is primarily valued in the aquarium trade for its vibrant colours. Breeders have developed many colour morphs. However, specimens raised in Singapore may carry a specific iridovirus. They are sometimes confused with thick-lipped gouramis when young.
