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.
In recent years, the word detritus has also come to be used with aquariums (the word "aquarium" is a general term for any installation for keeping aquatic animals). When animals such as fish are kept in an aquarium, they produce substances such as excreta, mucus, and dead skin cast off during moulting. These substances naturally generate ...
Found burrowing in mud or sand flats in the wild, they need a deep sand bed in their aquarium. 60 cm (23.6 in) Sea spider [3] Pycnogonids: No: Not collected for the aquarium trade, but occasionally seen on live rock and corals as a hitchhiker. They can be pests in a reef tank, preying on soft coral, sponges and anemones. 0.2–50 cm (0.1–19.7 in)
They are active throughout the day and can be seen grazing on biofilm, aquarium décor or the sides of the tank, hunting detritus among the gravel, and sometimes even mating. Periodically, a shrimp will shed its exoskeleton , leaving an empty white ghost of itself caught in the plants or drifting around the tank.
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
Freeze-dried and frozen fish foods were primarily developed for tropical and marine fish and are useful in providing variety to the diet or specialist feeding needs of some species. [4] These include tubifex worms, mosquito larvae, bloodworms, water fleas (Daphnia and Cyclops spp.) along with brine shrimp (Artemia salina). [citation needed]
Urechis unicinctus, known as the fat innkeeper worm or penis fish, [3] [4] is a species of marine spoon worm in East Asia. It is found in Bohai Gulf of China and off the Korean and Hokkaido coasts. [4] It is not to be confused with a closely related species, Urechis caupo, which occurs on the western coast of North America and shares common ...
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.
