Aphyosemion bualanumBouala Lyretail
Ahl, 1924
Max length50mm SL2.0in SLTanknot recordedTempnot recordedpHnot recordedDescribed from 'Buala, Cameroon', which corresponds to modern-day Bouala in Central African Republic. It's known distribution includes parts of northern Cameroon, western Central African Republic, southeastern Chad and possibly eastern Nigeria in the upper Benue and Mayo Kébbi river systems. The specific name was mis-used to refer to various populations of the congener A. elberti prior to 1990, and we've been unable to confirm if the specimen pictured here is correctly identified or not. It is listed as 'endangered' by the IUCN.

Betta miniopinna
Tan & Tan, 1994
Max length35mm SL1.4in SLTank45 × 30cm18 × 12inTemp22–28°C72–82°FpH4.0–6.0Bintan has been developed for tourism over the last decades and is heavily-promoted by Indonesia, with luxury beach resorts and golf courses increasing in number. Further deforestation has occurred in order to establish large rubber plantations in the interior of the island. B. miniopinna is now restricted to a few remaining pockets of primary peat swamp forest and has been listed as 'Critically Endangered' on the IUCN Red List of Threatened Species since 1996.

Devario acuticephalus
Hora, 1921
Max length40mm SL1.6in SLTank80 × 30cm31 × 12inTemp16–22°C61–72°FpH6.0–7.0Described from Manipur state, northeastern India and also known from neighbouring Nagaland state. In the original description Hora refers to it as 'widely-distributed' in the region but during an assessment conducted by the IUCN in 2010 it was recorded only from a handful of localities and restricted to an area of less than 15,000 square kilometres. Most habitats lie within the Manipur river basin, including the tributary Iril and Khuga drainages, and the Di...

Hemibagrus punctatusPorthole Bagrid
Jerdon, 1849
Max length197mm SL8in SLTanknot recordedTemp20–27°C68–81°FpH6.0–7.0Confirmed localities include the Kabini, Bhadra and Moyar tributary systems where it was last collected in 1998, the 1980s and 1990-92, respectively. The IUCN currently list it as Critically Endangered (possibly extinct).
Lates niloticusNile Perch
authority not recorded
Max length1930mm SL76in SLTanknot recordedTemp22–28°C72–82°FpH7.0–8.5This species has been introduced into many areas in Africa for commercial purposes, and it's had a hugely detrimental effect on local fish populations in some of these environments. The most notable case is that of Lake Victoria, where much of the endemic cichlid population has been wiped out. L. niloticus is thought to have directly contributed to the extinction of over 200 endemic species in the lake by predation, or outcompeting them for food. The IUCN have included it in their list of t...
Marosatherina ladigesiCelebes Rainbowfish
authority not recorded
Max length80mm SL3.1in SLTank76 × 30cm30 × 12inTemp22–28°C72–82°FpH7.0–8.0For many years, this species was included in the genus Telmatherina, and is still listed as such in much of the avilable literature. In fact it's now the only species in the recently erected genus Marosatherina. Unfortunately, it has been overfished for the aquarium trade in its native waters and is listed as 'vulnerable' on the IUCN red list of threatened species. Thankfully, it's now being mass-produced on fish farms in both the Far East and Eastern Europe, meaning that few...
Melanotaenia boesemaniBoeseman's rainbowfish
authority not recorded
Max length110mm SL4in SLTank120 × 30cm48 × 12inTemp27–30°C81–86°FpH7.0–8.0This uniquely-patterned species is one of the most popular rainbowfish in the hobby and can be found swimming in most dealers' tanks. However, virtually all these fish are mass-produced on fish farms in the Far East and Eastern Europe. M. boesmani is actually quite rare in nature, and is on the IUCN red list of endangered species. Unfortunately this is one species on which the aquarium trade has had a massively detrimental effect, with an estimated one million fish a year being collected to...
Melanotaenia gracilisSlender Rainbowfish
authority not recorded
Max length75mm SL3.0in SLTank75 × 30cm30 × 12inTemp22–28°C72–82°FpH7.0–8.0This uniquely-shaped rainbow is an uncommonly seen species in the hobby, mainly because it hails from such a remote area in Australia. It is currently listed on the IUCN list of threatened species as being at risk, so all attempts at captive spawning are to be encouraged....
Melanotaenia lacustrisLake Kutubu Rainbowfish
authority not recorded
Max length120mm SL5in SLTank120 × 30cm48 × 12inTemp20–25°C68–77°FpH7.0–9.0Unfortunately the prisitine environment form where this fish comes is being threatened by overfishing (much of it for the aquarium trade) and industry, with an oil development being built at one end of the lake during the 1990s. M. lacustris has therefore been given "vulnerable" status on the IUCN red list. The lake was designated a Wetland of International Importance in 1998, as both it and the Kikori Basin where it lies contain some of the earth's greatest biodiversity in terms ...
