Marble Spitzschwanzgurami ( Malpulutta kretseri )
The marble Spitzschwanzgurami ( Malpulutta kretseri ) is a freshwater fish species from the subordination of the labyrinth fish. It occurs in shallow streams in southwestern Sri Lanka.
Features
The marble Spitzschwanzgurami is a maximum of 7 cm long, but usually remains at a length of 2 to 4 cm. He has an elongated, moderately high-backed and laterally strongly flattened body and terminating in a pointed snout head. The dorsal fin is relatively short and is about the middle of the body, the anal fin is very long. The pelvic fins are directly below the pectoral fins. The basic color is brown, the fins edges iridescent bluish.
- Fins formula: Dorsal VIII-X/4-6, Anal XIII-XVII/7-11, pectoral 12, ventral I / 5, caudal 13-15.
- Dandruff formula: MLR 29-30.
Dorsal, anal and caudal fin running from a point. The weichstrahlige part of dorsal and anal fin is more extensive than the hartstrahlige.
Way of life
The marble Spitzschwanzgurami lives in clear forest streams with a gentle current. He stays mainly in the shore area between aquatic plants. The water in his living waters is soft and slightly acidic. The Perlmuttbärbling ( Rasboroides vaterifloris ) is found in the same habitat in part. Like all members of the Osphronemidae family runs the marble Spitzschwanzgurami brood care and lays its eggs in a foam nest. It feeds on zooplankton, insects and fish larvae.
System
The marble Spitzschwanzgurami was described in 1937 by the Ceylonese zoologists and paleontologists Paules Edward Pieris Deraniyagala and is the only species of the genus Malpulutta. The genus name is derived from the Sinhalese from ( "mal" = flower, " pulutta " = Cat. Bez for the Ceylonmakropoden ( Belontia signata ) ). The Style epithet kretseri honors the Ceylonese lawyers de Kretser, which the fish discovered in 1937 and gave to Deraniyagala for determination. Malpulutta kretseri is placed in the subfamily Macropodusinae, which is the sister group of the gouramis.
Endangering
The species is not classified by the IUCN as endangered.
