Results for “gravel”

Predominantly a riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, typically flowing through tropical forest. In the habitat seen in our images sympatric fish species included Barbonymus balleroides, B. collingwoodi, Cyclocheilichthys repasson, C. apogon, Diplocheilichthys pleurotaenia, Garra borneensis, Leptobarbus hosii, and an unidentified Gastromyzon sp.

Predominantly a riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, and apparently displays a preference for deeper, slower-moving stretches. In Sabah such habitats typically flow through tropical forest, although in recent years freshwater habitats throughout much of the state have been extensively modified by human activity such as conversion to palm or rubber plantations.

A predominantly riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, where adults tend to form schools just above the substrate in slower-moving sections.

Collected from small streams flowing through savanna grassland containing clear, light brown-coloured water with substrates of sand and gravel and little in the way of submerged or riparian vegetation. At the type locality pH varied between 5.8 – 6.3, GH and KH were both <1°, conductivity was 9-13 μs and temperature 24.7 – 27.2°C/76.6 – 80.1°F.

Should be kept in a set-up designed to resemble a flowing stream with a substrate of variably-sized rocks, gravel and some water-worn boulders. This can be further furnished with driftwood roots and branches arranged to form some shaded spots while lengths of PVC piping or similar can be used to provide additional cover. Although most plant species will fail to thrive in such surroundings hardy genera such as Microsorum, Bolbitis or Anubias spp. can be grown attached to the décor and bright lighting will promote the growth of aufwuchs.

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.

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,...

Inhabits well-oxygenated, low-to-medium gradient, slow to moderate-flowing rivers and streams with substrates of gravel, cobbles, larger boulders and exposed bedrock. At the habitat in our image pH was 7.5, temperature 26°C and cond...

Not difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to simulate a flowing stream with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders. This can be further furnished with driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots, thus providing broken lines of sight.

A benthopelagic fish mostly recorded from streams and minor tributaries at relatively high altitudes of more than 1200 metres AMSL with cool, clear, well-oxygenated water and substrates of bedrock, boulders, cobbles, and gravel. Aquatic plants aren't usually present though riparian vegetation may be well-developed. It's also present in some ponds and small lakes, including some stagnant water bodies with muddy substrates.

The type series was collected from a small clear-water stream with a pH of 6.0, forming a series of riffles and deeper pools, with a maximum width of 5 metres and depth ranging from 10 cm to 1 metre. The substrate was composed of sand gravel and rocks, with some leaf litter and overhanging marginal vegetation.

The hill streams in which this fish can be found are generally shaded by the forest canopy and dense marginal vegetation. Substrates are typically composed of boulders, smaller stones, sand or gravel with submerged tree roots around the margins and quieter areas in which fallen branches and leaf litter collect. Other fish species occurring in the Tunga...

Presumably inhabits small rivers, tributaries and streams with substrates of gravel, rocks, boulders, and exposed bedrock which undergo seasonal variations in water flow rate, depth and turbidity. Lanyu Island is volcanic, measures just 45 km² and has no major rivers or large settlements with a permanent human population of around 4000, although there is a large nuclear waste storage facility at its southern end.

Appears restricted to highly-oxygenated, fast-flowing riffles of small-to-medium sized streams. These typically contain clear water with substrates of gravel, rocks, boulders, and bedrock with no aquatic plants.

Should not prove difficult to maintain under the correct conditions. We strongly recommend keeping it in a tank designed to resemble a flowing stream or river with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders. This can be further furnished wit...
