Ptychochromis loisellei is a species of cichlid from the Mahanara River basin north of Sambava in northeastern Madagascar. It remains common within its small range, but it is threatened by habitat loss and introduced species. It reaches about 11.9 centimetres (4.7 in). The similar named Paretroplus loisellei is also restricted to the Mahanara River basin. The specific name honours Paul V.

Schistura khamtanhi is a species of ray-finned fish in the genus most speciose genus in the stone loach family, Schistura. It is found in the Kong River basin in Laos and in the main Mekong river in Cambodia and Laos where it is abundant, being an important quarry species for the fish traps at Kohne Falls. It inhabits rapids and Sony bottomed stretches of the main Mekong and its tributaries and it migrates past the Kohne Falls in January and February annually. It is the only member of the genus Schistura which is known to be migratory. The specific name honours Khamtanh Vatthanatham, a Fisheries Programme Officer of the Mekong River Commission who was very helpful to the Maurice Kottelat during his 1999 survey, in which this species was discovered.
Schistura nicholsi is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the Mekong basin of north eastern Thailand, Laos and it is also likely to be found in Cambodia. It occurs in shallow riffles with moderate to fast flows. Human modification of the rivers' morphology through such activities as logging and agriculture are affecting this species range. However, its distribution covers a wide geographic range and it is assessed as Least Concern by the IUCN. The specific name honors John Treadwell Nichols (1883-1958) who was curator of fishes at the American Museum of Natural History and who made an important contribution to the ichthyology of China, and especially to the knowledge of loaches.
Schistura poculi is a species of ray-finned fish, a stone loach, in the genus Schistura. This species of stone loach is currently thought to occur in the basins of the Mekong, Salween and Chao Praya rivers in Myanmar, Thailand and Laos. However, these may refer to more than one species, in which case the name S. poculi belongs to the population in the Chao Praya. It can be found in streams with moderately fast to fast currents among riffles where there are substrates which vary from gravel to stone. The specific name poculi means "bowl" and refers to the type locality, Doi Angkon in Thailand with angkon meaning "crow's bowl".
Schistura porthos is a species of ray-finned fish in the stone loach genus Schistura from the Mekong basin; the Nam Ngiap, Nam Khan, Nam Xuang, Nam Ou and Nam Tha drainages in northern Laos and the Luosuojiang drainage in Xishuangbanna, Yunnan. The specific name comes from one of Alexandre Dumas' The Three Musketeers, Aramis as do that of two other Schistura species endemic to the Nam Ou basin, S. athos and S.aramis.
Betta enisae is a species of gourami endemic to the Kapuas River basin of Indonesia. It is an inhabitant of forest streams with slightly acidic waters, and can mostly be found in the shallows amongst the leaf litter. This species grows to a length of 5.9 cm (2.3 in). It is commonly used as bait by local fishermen and has been found in the aquarium trade. The specific name of this fish honours Enis Widjanarti who assisted Kottelat in his expedition to the Kapuas Lakes.
The Mexican rivulus is a species of killifish from the family Rivulidae which is endemic to Mexico where it is found in the Papaloapan and Coatzacoalcos River basins. This annual killifish grows to a total length of 4 cm (1.6 in). It is the only known species in its genus, but its exact taxonomic position remains uncertain, as it has not been included in any phylogenetic study. This species was described by Robert Rush Miller and Carl Leavitt Hubbs as Rivulus robustus in 1974, it was reclassified in the monotypic genus Millerichthys in 1995, the generic name honouring Robert Rush Miller.
Orthochromis stormsi is a species of cichlid endemic to the Democratic Republic of the Congo, where it is known from the upper Congo River basin and Lake Mweru. It has also been reported from Pool Malebo and the Regina Falls in the lower Congo River basin, but the identity of these populations requires further investigation. This species can reach a length of 10.2 centimetres (4.0 in) SL. The specific name hours the Belgian Army Lieutenant Maurice Joseph Auguste Marie Raphael Storms (1875-1941) who collected the type which he presented to the Brussels Museum.
