Results for “transparent”

The type locality is an area of permanently-flooded grassland formed by the damming of a spring for agricultural purposes. The water is only around 30cm deep, transparent and supports dense growths of aquatic plants, mostly from the family Hydrocharitaceae which includes such genera as Elodea, Egeria and Blyxa. Sympatric species included Devario sondhii, a Microrasbora very similar to M. rubescens, an undescribed Yunnanilus known to aquarists as the 'rosy' loach and Channa harcourtbutleri.

This species appears superficially similar to a number of congeners including C. ambiacus, C. agassizii, C. brevirostris, C. delphax, and C. melanistius. Among these C. ephippifer seems to be unique in that all fins except the dorsal are transparent and lack markings.

The habitat near Hopong is an area of permanently-flooded grassland formed by the damming of a spring for agricultural purposes and is around 1,040 metres AMSL. The water is only around 30cm deep, transparent and supports dense growths of aquatic plants, mostly from the family Hydrocharitaceae which includes such genera as Elodea, Egeria and Blyxa.

This species appears to be a relative ecological generalist. During a sampling trip in 1989 it was collected various habitat-types including a narrow (maximum width 3 m) stream containing shallow (maximum depth 1 m), transparent, moderate to fast-flowing water and substrate comprising gravel, mud, clay and organic debris including submerged logs. Aquatic plants consisted of water lilies and marginal vegetation was dense, comprising various trees, shrubs, grasses and ferns.

G. filamentosa has appeared in the ornamental trade but is evidently delicate and therefore recommended only to experienced aquarists. It can be told apart from congeners by the following combination of characters: possession of filamentous dorsal and anal-fin rays in males; body transparent to translucent yellowish-brown colour in life; absence of a highly-extended second anal-fin spine; absence of carmine-red pigmentation in the dorsal, anal an...

Apparently inhabits calm to moderately-flowing stretches of well-oxygenated headwaters and minor tributaries. Such habitats tend to comprise transparent water, substrates of sand, gravel, rocks, boulders, and patches of leaf litter, with submerged driftwood, roots of riparian vegetation, and aquatic vegetation in places.

An incredibly-adapted species, this fish is camouflaged to mimic a dead leaf, both in body shape and pattern. It can change colour to match its surroundings and has a projection from its bottom lip that resembles a leaf stalk. When hunting, it stalks its prey in a head-down stance, appearing to drift towards it like a dead leaf drifting in a current. In reality, the fish is propelled by tiny movements of its transparent fins. When it strikes at an item of prey the entire mouth protrudes outwards...

This species may have appeared in the aquarium trade though probably not under the correct name. It can be told apart from similar-looking congeners by the following combination of characters: presence of a black round spot at the caudal base; dorsal-fin rays black with connecting membranes transparent; posterior dorsal-fin origin located midway between upper angle of gill aperture and caudal-fin base, or slightly closer to the latter.

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...

Like the closely related Polycentrus species from South America, with which it is sometimes confused, this fish is camouflaged to mimic a dead leaf, both in body shape and pattern. It can also change colour to match its surroundings. When hunting, it stalks its prey in a head-down stance, appearing to drift towards it like a dead leaf drifting in a current. In reality the fish is propelled by tiny movements of its transparent hind fins. When it strikes at an item of prey, the entire mouth pro...
