The growling gourami ( Trichopsis vittata ( lt .: "vittatus" = banded)) belongs to the subordination of the labyrinth fish . The fish are found in Southeast Asia in Thailand , Laos , Cambodia and Vietnam , on the Malay Peninsula and in Singapore . Populations in the Philippines were introduced by humans. Trichopsis populations on Sumatra , Borneo and Java are currently assigned to Trichopsis vittata , but may represent a separate species ( Trichopsis striatus ).
description
The growling gourami is a maximum of 7 cm long, but usually remains much smaller. His body is elongated and heavily flattened on the sides. The unpaired fins are long and often have a few elongated fin rays . The anal fin can extend with its elongated fin rays to the end of the caudal fin. The basic color is yellowish to brownish, with the back darker and the belly yellowish white. Depending on the lighting conditions, the sides can shimmer bluish white. There are 2 to 4 dark brown longitudinal bands on the sides of the body. Two start at the back of the eye. The fins are reddish to purple or bluish and patterned with red and green dots.
- Fins formula : dorsal II – IV / 6–8, anal VI – VIII / 24–28, ventral I / 5, pectoral 11.
- Scale formula : mLR 28–29.
Way of life
Growling guramis inhabit small pools, swamps, rice fields and ditches with warm water, densely overgrown with herbaceous plants, and feed on zooplankton, small crustaceans and insect larvae. Like many labyrinth fish, the growling gourami builds a foam nest for reproduction . It is only small and is supported by dense aquatic plants deep below the surface of the water. The female lays up to 600 eggs that sink to the ground, which the female, sometimes also the male, collects and spits into the nest. The fry hatch after about 24 hours.
