When their population becomes high, the worms migrate toward the surface of the water for access to higher concentrations of oxygen. [citation needed] Although detritus worms may not cause harm to aquarium fish, their appearance is an indication of poor water quality mainly due to overfeeding and lack of good water sanitation. [5]
Horse feces and straw are forms of detritus, and are used as manure. In biology, detritus (/ d ɪ ˈ t r aɪ t ə s / or / d ɛ ˈ t r ɪ t ə s /) is organic matter made up of the decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decompose (remineralise) it.
They feed on detritus, sucking up organic particles with their muscular pharynx. They are hermaphrodites, the marine species producing eggs which develop directly into miniature adults. The freshwater species are parthenogenetic, producing unfertilised eggs, and at least one species is viviparous. Gastrotrichs mature with great rapidity and ...
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).

Detritivores (also known as detrivores, detritophages, detritus feeders or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). [1] There are many kinds of invertebrates, vertebrates, and plants that carry out coprophagy.
This is done by paratomy (fragmentation), when the posterior segments are separated from the parent worm. It starts when the worm reaches a certain number of millimeters (depending on the species). [5] Only one species, Aeolosoma singulare, is known to reproduce sexually. [6] Aeolosoma feed on microalgae, microorganisms and detritus. [7]
The Aeolosomatidae is a family of very small, aquatic annelid worms, between 0.3 and 10 mm in length and 0.04-0.06 mm in diameter. About 30 species have been described in three genera . [ 2 ] These worms are known as suction-feeding worms and occupy freshwater, brackish, and saltwater habitats.
