The ricefishes are a family (Adrianichthyidae) of small ray-finned fish that are found in fresh and brackish waters from India to Japan and out into the Malay Archipelago, most notably Sulawesi. The common name ricefish derives from the fact that some species are found in rice paddies. This family consists of about 37 species in two genera. Several species are rare and threatened, and some 2–4 may already be extinct.
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. A river flows from the lake to the Boni Bay. The town Laronda is located on its shore.
Lake Matano, also known as Matana, is a tropical lake in East Luwu Regency, South Sulawesi province, Indonesia, that is noteworthy for the unique environment in its deeper layers.
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.
The sharp-jawed buntingi is a species of ricefish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia.
Xenopoecilus is a genus of small fish in the family Adrianichthyidae. All members of the genus are threatened and endemic to lakes in Sulawesi, Indonesia. Pollution and the introduction of other fish into the lakes are the main reasons for the fall in Xenopoecilus numbers.
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' in the aquarium trade.
Tylomelania is a genus of freshwater snails which have an operculum, aquatic gastropod mollusks in the family Pachychilidae. In the aquarium hobby, snails from this genus are commonly known as "rabbit snails".
Adrianichthys is a genus of ricefishes. The genus is endemic to Lake Poso in Sulawesi, Indonesia. All four species are considered seriously threatened and two of these, A. kruyti and A. roseni, have not been recorded for decades, leading to fears that they already are extinct. Adrianichthys are larger than the Oryzias ricefish, reaching lengths of 8.5–17.1 cm (3.3–6.7 in) depending on the exact species involved. The name of this genus is a compound ending in the Greek ichthys for "fish" with the first part honouring the linguist and missionary Nicolaus Adriani (1865-1926), who collected specimens around Lake Poso.
Tylomelania toradjarum is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pachychilidae.
Tylomelania scalariopsis is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pachychilidae.
Tylomelania carbo is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pachychilidae.
Dennerle is a German company producing aquarium and pond supplies. It was founded in 1966 as a pet store by Ludwig Dennerle in Pirmasens.
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 woltereckae, or Sulawesi harlequin shrimp as it is commonly known in the aquarium hobby, is a freshwater shrimp from Sulawesi, Indonesia. It is endemic to Lake Towuti. It resembles the smaller and less contrastingly coloured Caridina spongicola, which is endemic to the same lake.
Adrianichthys roseni is a species of ricefish, a member of the family Adrianichthyidae which is endemic to Lake Poso on Sulawesi. Since the holotype was collected in 1978 there have been no reports of this species and if it still exists then it has a very low population. The IUCN categorise it as Critically Endangered.
Caridina glaubrechti is species of lacustrine fresh water shrimp endemic to western part of Lake Towuti on the Indonesian island of Sulawesi. It is named in honor of German Zoologist Matthias Glaubrecht.
Caridina holthuisi is a species of freshwater shrimp in the family Atyidae, endemic to the Malili lake system in Sulawesi, Indonesia. It can be found in Lake Towuti, Lake Matano, and Lake Mahalona, as well as the Petea river. It is named in honour of Dutch carcinologist, Lipke Holthuis.
Caridina longidigita, also known as the Sulawesi fan shrimp, is a species of freshwater atyid shrimp.
Caridina sarasinorum is a species of freshwater atyid shrimp. It is one of eight Caridina species endemic to Lake Poso.
