Caridina multidentata is a species of shrimp in the family Atyidae. It is native to Japan and Taiwan. [1] Its common names include Yamato shrimp, Japanese shrimp, Amano shrimp, and algae shrimp. [2]
Caridina multidentata are freshwater shrimp in the Atyidae family and are commonly found in southwestern Japan. [3] [4] They typically grow to 25-35 millimetres. This species of shrimp is amphidromous. Oviposition and hatching occurs in freshwater, and newly hatched larvae drift to saltwater and develop as juveniles, returning to freshwater in their adult forms. [3] The eggs of Caridina multidentata are rich in yolk and are oval-shaped. [5]
The species has adapted to live in fast-flowing water, having a wide and short rostrum. Caridina multidentata begin to take in food in the third zoeal stage, relying on internal nutrition longer than distant relatives such as the Caridina leucosticta and Caridina typus . They have a large geographic distribution, suggesting high levels of larval dispertion. [4] This species has a translucent body covered with a broken line of reddish brown points on its sides. The dorsal surface has a white stripe that runs from the head to the tail and the eyes are black. Females are easily distinguished from males by their more elongated lower row of dots.
Caridina multidentata fare best in temperatures of 18 °C to 28 °C (approximately 64 °F to 82 °F). They are more active at higher temperatures, but may also have a shorter lifespan. They prefer a pH of 6.5 to 7.5. As with all crustaceans, they are extremely averse to copper due to their haemocyanin blood. [6]
Caridina multidentata was introduced into the world of aquaria by Takashi Amano in the early 1980s. They are usually used in an aquarium because they feed primarily on algae, thus cleaning the aquarium of it when present in sufficient numbers. Caridina multidentata was previously known to aquarists as Caridina japonica but was renamed Caridina multidentata following a study in 2006. [7] [8]
Many aquarists believe that Amano shrimp can sustain themselves on algae in the aquarium alone, however, this is not the case. Amano shrimp thrive best on a diet of aquarium algae supplemented by algae wafers or spirulina flakes and occasional animal-based protein in the form of pellets, flakes, or frozen or live daphnia, mysis, and more.[ citation needed ] It is also necessary to ensure there is calcium present in the water, as calcium is vital to crustaceans in order for them to maintain their exoskeleton.
Amano shrimp are notoriously difficult to breed in captivity, [9] [ better source needed ] as their young require a higher water salinity than the adults to survive. This means that virtually all amano shrimp in the pet trade are wild caught, since captive breeding is not considered economical.
The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
Caridina is a genus of freshwater atyid shrimp. They are widely found in tropical or subtropical water in Asia, Oceania and Africa. They are filter-feeders and omnivorous scavengers. They range from 0.9 to 9.8 mm to 1.2–7.4 mm in carapace length.
Atyidae is a family of shrimp, present in all tropical and most temperate waters of the world. Adults of this family are almost always confined to fresh water. This is the only family in the superfamily Atyoidea.
Takashi Amano was a professional Japanese track cyclist, photographer, designer, and aquarist. He founded Aqua Design Amano (ADA), a Japanese company that specializes in the design of aquariums and their production.
Lake Towuti is a lake in East Luwu Regency, South Sulawesi province, Indonesia. Surrounded by mountains, it is the largest lake of the island of Sulawesi and one of the five lakes of the Malili Lake system. The Larona River flows from the lake to the Boni Bay. The town Laronda is located on its shore.
Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. They are also important primary consumers that relay the biomass and energy from photosynthetic autotrophes up into the food web, as well as protecting the aquatic ecosystem against algae blooms.
Syncaris pasadenae is an extinct species of freshwater shrimp in the family Atyidae.
Troglocaris is a genus of freshwater shrimp in the family Atyidae. These stygobitic, whitish and eyeless shrimp are found in Southern Europe. Although locally very common, the small ranges of the individual species make them highly vulnerable to habitat loss, for example by water extraction. Their underground habitat is often extremely stable; for example, the Vipavska jama cave in Slovenia is home to a population of T. anophthalmus, and its water only varies from 10 °C (50 °F) in the winter to 11 °C (52 °F) in the summer. In some Dinaric caves, notably Vjetrenica, as many as three species may occur together.
Neocaridina davidi is a freshwater shrimp originating from eastern China and northern Taiwan and introduced in the rest of Taiwan, Japan, and Hawaii, which is commonly kept in aquaria. The natural coloration of the shrimp is green-brown, though a wide variety of color morphs exist, including red, yellow, orange, green, blue, violet and black shrimp. Full-grown shrimp reach about 4 centimetres (1.6 in) long. N. davidi shrimp are omnivores that may live 1–2 years. These shrimps have previously been classified as Neocaridina heteropoda and Neocaridina denticulata sinensis, however are now known as Neocaridina davidi which is based on the oldest known published description of the species.
Caridina gracilirostris is a species of brackishwater shrimp belong to genus Caridina in the family Atyidae. It has a wide native range extending from Japan and Fiji through Indonesia to Madagascar. It is an algae-eating species that lives in mangroves and marshes. Its common names include red front shrimp, red rhinoceros shrimp, red nosed phantom shrimp, and needlenose caridina, red nosed shrimp.
Caridina dennerli is a small species of freshwater shrimp from Sulawesi (Indonesia) that grows up to 2.5 centimetres (1.0 in) in length. It takes its name from the German company Dennerle, which supported the expedition that led to the scientific description of the species. It is popularly known as the cardinal shrimp or Sulawesi shrimp in the aquarium trade.
Caridina thambipillai is a species of freshwater shrimp in the family Atyidae. It is native to Malaysia and Myanmar, where it occurs in streams. It is a common crustacean of the freshwater aquarium trade, where it is known as the Sunkist shrimp.
Caridina mariae, commonly known as the tiger shrimp, is a variety of freshwater shrimp from Southeast Asia that are popular in hobby aquariums. The natural coloration of the shrimp isa semitransparent body, with dark brown to black blotches on the carapace, and dark brown to black "tiger" stripes along the posterior part of the carapace and along the first six abdominal segments. Variations of the species may also have orange eyes, and orange highlights in the tail fins. There is also a lack of dark markings on the tail fan
The bee shrimp, is a species of small freshwater shrimp in the family Atyidae. It is native to Taiwan. These shrimp are scavengers, and eat small pieces of decayed vegetation and algae. Bee shrimp have a life span of about 18 months. They enjoy a temperature in the 70 to 78 °F range. Many modern versions of bee shrimp are selectively bred for their characteristics.
Caridina spongicola is a small species of freshwater shrimp from Sulawesi (Indonesia) that reaches 0.64 to 1.27 cm in length. In the wild it strictly lives on an undescribed species of freshwater sponge, making it one of only two known commensal species of freshwater shrimp. It is popularly known as the harlequin shrimp, and also sometimes Celebes beauty shrimp or sponge shrimp in the aquarium trade. It is often confused with Caridina woltereckae, a larger and more contrastingly colored species found in the same region as C. spongicola.
Caridina linduensis is a species of freshwater shrimp in the family Atyidae, endemic to Lake Lindu and its effluent stream in Sulawesi. It was known only from the type series, collected in 1904, and was recorded again in 2011 in a survey around Lake Lindu and is found in shallow littoral habitats of leaf litter, macrophytes, and dead wood. In the effluent stream it is found on soft substrates and slow flowing water, and is less common in the lake itself. The type locality of Lake Lindu was designated as a Recreation Park in 1978, and is part of the larger Lore Lindu National Park and UNESCO Biosphere Reserve. It is listed under IUCN criterion B1ab(iii,v) as Critically Endangered due to threats from introduced species of fish, land conversion to agriculture, logging, and shore disturbance caused by the grazing of water buffalo. Surveys are required to find the full distribution of C. linduensis, primarily its habitat in the effluent stream. C. linduensis is also sympatric with the recently described species Caridina dali and Caridina kaili.
Feeder shrimp, ghost shrimp, glass shrimp, grass shrimp, river shrimp or feeder prawns are generic names applied to inexpensive small, typically with a length of 1 to 3 cm, semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
Caridina typus, also known as the Australian Amano Shrimp, is a species of amphidromous atyid shrimp. It was first described by H. Milne-Edwards in 1837. It has a broad distribution in tropical freshwater habitats in the Indo-West Pacific region, with its western range extending to eastern Africa and its eastern range extending to Polynesia. It is commonly found in rivers and streams in coastal areas or on islands. C. typus is known to play a role in sediment distribution and shredding leaf litter, manipulating the environment using their pereiopods and setaceous chelae. The species is also an important component of the food web, both as scavengers and as prey items, and is considered a keystone species for the stream ecosystems it inhabits. According to Choy and Marshall, the species can be characterized by a "short, dorsally unarmed rostrum, the presence of epipods on the first four pairs of pereiopods, and the presence of an appendix interna on the endopod of the first pleopod of both sexes." It can be kept in captivity by aquarists as pets.
