What it is
This fish belongs to the gourami group and is the sole member of its genus. It has a compact body that grows to four centimetres at most, though two centimetres is more typical. The species lives in fresh water within dense forest environments. Its appearance suits the dim light of shaded banks where it hides among plants and fallen leaves.
Where it lives
The ornate paradisefish occurs only in Sri Lanka. It prefers shallow waters that move slowly through wooded areas. These habitats feature heavy shade from overhead trees and abundant vegetation along the edges. The stream bed is usually covered with decaying leaf litter, which provides cover and hunting grounds for this small creature.
How it lives
It feeds on meat rather than plants. The diet includes tiny drifting organisms, young fish, and insect larvae found in the water. This carnivorous habit helps it survive in nutrient-poor forest streams. The fish is known for being exceedingly shy, often hiding from view in its natural habitat or when kept in captivity.
Fish and people
Aquarium keepers sometimes import this species for home tanks. Its small size and unique status as a Sri Lankan endemic make it interesting to collectors. However, its shy nature means it may remain hidden much of the time. There are no widespread reports of it being used for food or traditional medicine.
