Aqualognews NUMBER 96 2 T he genus Moenkhausia contains characins that have traditionally been among the most popular of aquarium fishes. There can be hardly a pet shop in the world that doesn’t stock at the very least the Red-Eye Tetra (M. sanctaefilomenae) as a representative of its genus. A first import! Aquarium Glaser have now imported small numbers of a very unusual tetra, Moenkhausia cosmops, from Brazil for the first time.This species was first scientifically described in 2007. To date it is known only from the upper reaches of the Rio Paraguay and Rio Tapajos basins in the state of Mato Grosso: Rio Juba, Rio Juruena, Rio Papagaio,and their tributaries. The closest relations of the new species Its nearest relatives are thought to be the Glass Tetra, Moenkhausia oligolepis,and the Red-Eye Tetra, M. sanctaefilomenae, both TETRAS A new star in the characin sky - Moenkhausia cosmops by Wolfgang Löll Characins are an immensely varied group of fishes. They include the tiny,prettily-colored fellows such as the neon tetras, much-dreaded predators such as the piranhas,and every imaginable form in between. The “moustache”of the species is very striking. Moenkhausia cosmops All Photos: Frank Schäfer well-known in the aquarium hobby. The other similar species - M. cotinho, M. diktyota, M. forestii,and M. pyrophthalma – have to date been unimportant in the hobby. All these species share the common features of a red iris and a caudalpeduncle spot. M. cosmops can be distinguished at first glance from the species named above by virtue of its bluegreen eyes and the red stripe above the mouth. No other species looks the same The unique coloration of this species is slightly reminiscent on the one hand of the gorgeous emperor tetras (Nematobrycon), and on the other of the Lipstick Barb (Barbus erythromycter) from Asia. But there is no phylogenetic relationship with the species named. Uncomplicated maintenance A readily recognizable characteristic:the blue eyes. The maximum length of Moenkhausia cosmops is around 6 cm. These fishes are somewhat timid initially.To date they have proved fairly hardy and peaceful. Like the majority of tetras they are unproblematical when it comes to feeding. Investigation of stomach contents in the wild revealed insects (mainly ants),
