The emerald shiner is one of hundreds of small, silvery, slender fish species known as shiners. The identifying characteristic of the emerald shiner is the silvery emerald color on its sides. It is found across North America from Canada to the Gulf of Mexico, commonly in large, deep lakes and rivers, though sometimes in smaller bodies of water as well. It feeds on small organisms such as zooplankton and insects, congregating in large groups near the surface of the water. It is a quite common fish and is often used as a bait fish.
The fauna of Indonesia is characterised by high levels of biodiversity and endemicity due to its distribution over a vast tropical archipelago. Indonesia divides into two ecological regions; western Indonesia which is more influenced by Asian fauna, and the east which is more influenced by Australasian species.
Lake Towuti is a lake in East Luwu Regency, South Sulawesi province, Indonesia.

The red-tailed silverside, or zona is a species of Madagascar rainbowfish endemic to the Mananjary River drainage in Madagascar. It is threatened by habitat loss and introduced species. It has often been confused with the related B. madagascariensis, which is common in the aquarium trade. In addition to meristics, the two can be separated by the exact colour pattern on their tail fin and the distinct red spot on the lower jaw of breeding male B. geayi. B. geayi was described in 1907 by Jacques Pellegrin from a type collected by the pharmacist and natural history collector Martin François Geay (1859-1910), who Pellegrin honoured with its specific name.
Glossogobius flavipinnis is a species from the family Gobiidae endemic to Lake Towuti in Sulawesi, Indonesia,> where it is generally found at shallow depths over hard bottoms. This species can reach a length of 8 cm (3.1 in) TL, although in a review of museum specimens the largest male was only 3.9 cm (1.5 in) and the largest female 5.7 cm (2.2 in). It is overall uniform dark with a yellow first dorsal fin. It was previously known under the name Stupidogobius flavipinnis.
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.
Oryzias profundicola, the yellow-finned medaka or yellow-finned ricefish, is a species of fish in the family Adrianichthyidae.
Paratherina wolterecki is a species of fish in the subfamily Telmatherininae, part of the rainbowfish family Melanotaeniidae. This species is endemic to Lakes Towuti and Mahalona on the Indonesian island of Sulawesi. It reaches up to 15 cm (5.9 in) in total length. Their environment is pelagic and they live in tropical climates. It has the characteristic of having a mouth pointed upward. The specific name honours the hydrologist and biologist Richard Woltereck (1877-1944), who collected specimens of all four species in the genus Paratherina and who sketched them from life.
Telmatherina abendanoni is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia where it occurs only in Lake Matano on the island of Sulawesi. The specific name honours the Dutch malacologist and mining engineer Eduard Cornelius Abendanon (1878-1962), who was the leader of the Central Celebes Expedition of 1907–1918, on which the type was collected.
Telmatherina is a genus of sailfin silversides endemic to the Indonesian island of Sulawesi. They are restricted to the Malili Lake system, consisting of the large Matano and Towuti, and the small Lontoa (Wawantoa), Mahalona and Masapi. They are also found in rivers and streams that are part of this lake system.
Telmatherina antoniae is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia where it occurs only in Lake Matano on Sulawesi. The species was described in 1991 by Maurice Kottelat and its specific name honours his wife, Antonia.

Telmatherina wahjui is a species of fish in the subfamily Telmatherininae, which is part of the family Melanotaeniidae; the rainbowfishes. It is endemic to Indonesia, where it occurs only in Lake Matano on the island of Sulawesi. It can reach a maximum length of around 5 centimetres (2.0 in). This species was described in 1991 by Mairice Kottelat with a type locality of Alaponkepi which is situated at the outlet of Lake Matano. The specific name honours Beni N. Wahju who was Vice President and Secretary of P. T. Inco Industries. Mr Wahju's support was vital in ensuring that the ichthyological survey of the Malili Lakes, in which the type of this species was collected, was possible.
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".
