Results for “sympatric”

Sympatric fish species in the grasslands include Rivulus schuncki, juveniles of Hoplerythrinus unitaeniatus and an unidentified Nannostomus sp. One contrasting locality was a flowing igarapé with the fish collected from shallow water alongside Apistogramma gossei, Crenicichla inpa,unidentified...

Predominantly a riverine fish favouring clear, well-oxygenated, running water with substrates of sand or gravel and often present in rock and boulder-filled headwater streams. In the Mun River, close to the Pak Mun dam, Thailand, sympatric species included Hampala dispar, Cyclocheilichthys apogon, Osteochilus hasseltii,...

The type locality is a karst pool around 30-40 m in length, 10m in width and up to 4 m deep. It contains still, transparent water, has a single inflow and outflow, is surrounded by rainforest and in September 2010 the water temperature was 21.5°C/70.7°F. The habitat is used by locals as a bathing pool and sympatric species included a nat...

This species has something of a confused history having been previously been considered synonymous with both A. sophiae (a separate species native to Iraq and Iran) and A. cypris (currently considered a junior synonym of A. mento). Although some populations occur close to and even sympatric with other members of the genus in Turkey phylogenetic studies have shown it to be more closely-related to the Middle Eastern species A. dispar dispar, A. d. richardsoni, A. ginaonis and A. sirhani. It's...

The type locality is a stream with a mixed substrate of mud and stones which flows swiftly through an area of bamboo forest so is quite well-shaded. At time of collection the water was clear but slightly tannin-stained and sympatric species included Pethia thelys, Puntius sophore, Devario strigillifer, Rasbora daniconius, R. rasbora, Acanthocobitis botia, Notopterus notopterus, plus unidentified species of Oreichthys, Parambassis, Xenentodon, and Mastacembelus.

R. borapetensis is one of the more commonly-encountered rasboras in stores and is particularly recommended for newcomers to the hobby. While it can appear a little plain or 'washed' of colour when seen on sale once settled and in good condition it is an eye-catching little fish that often schools quite closely. It's sometimes sold with the alternative trade names of black-line or magnificent rasbora. R. rubrodorsalis is a very similar-looking congener that occurs sympatrically...

R. rubrodorsalis occurs sympatrically with the very similar-looking R. borapetensis over some of its natural range but is much the rarer of the two in the aquarium hobby. They are easily distinguishable from one another because R. rubrodorsalis has a bright red blotch in thewhilst in R. borapetensis the dorsal is colourless and only the base of the is coloured red. This species is sometimes sold under the erroneous name(s) R. beauforti or R. sp. cf. beauforti, probably because it was picture...

On Koh Chang one habitat consisted of a stream flowing from the waterfall Nam Tok Mai Yom which empties into the Gulf of Thailand after less than 1 km. The stream was dry in its lower reaches and had a substrate of boulders and pebbles. Sympatric fi...

The type locality originally consisted of a shallow (0.5 - 1.5 m deep) stream with a substrate of rocks and boulders and flow varying from 'moderate to swift'. When the holotype was collected there in 1980 sympatric species included Acanthocobitis zonalternans, Puntius orphoides, Pethia ticto, Raiamas guttatus, Barilius barnoides, Mystacoleucus argenteus and Mastacembelus armatus plus unidentified members of Crossocheilus an...

At the type locality of the congener S. lixianjiangensis sympatric species included Balitora kwangsiensis, Glyptothorax quadriocellatus, Garra orientalis, Hemibagrus pluriradtus, Poropuntius huangchieni, Pseudecheneis paviei,...

This species occurs in several colour forms depending on collection locality with some exhibiting more intense pigmentation in the fins or an additional reddish lateral stripe, for example. It's sometimes said to closely resemble and occur sympatrically with Rasbora agilis, but that name is currently considered a junior synonym of the congener Trigonopoma pauciperforatum. R. agilis had previously been us...

A single male of the Tequila Splitfin was sampled in 1955 by Miller and Greenbank, but identified erroneously as Zoogoneticus quitzeoensis, with which species it was collected and found sympatrically . Many years later, the mistake was detected, the fish identified as a new species and finally, 43 years after the first capture, described by Webb and Miller. In 2001, a wild population of this species was rediscovered in a very small spring pool (3 x 4m in diameter). The population there was composed of only a handful of adult fish and a few tens of juveniles (De la Vega-Salazar et al., 2003). In 2007, N. W. Bailey et al showed, that the allelic richness of this population (though it was comparable in size to an aquatic stock) was higher than in any aquatic stock. In 2013 the loss of this population was reported (pers. comm. Domínguez), so there is not much hope that this species is still persisting in the wild.
