Aplocheilus is a genus of killifish in the family Aplocheilidae. Their native range is in South and Southeast Asia, from India to Vietnam and Malaysia, and from Nepal to Sri Lanka. Several species, especially the striped panchax, A. lineatus, are important aquarium fishes.
The striped panchax is a species of killifish, of the genus Aplocheilus. An aquarium variant of this species with a more yellowish coloration is known as golden wonder killifish. The striped panchax inhabits fresh and brackish waters of India and Sri Lanka. It is found in streams, rivers, swamps, and paddy fields. This fish grows to a length of 10 cm (4 in). Most male A. lineatus measure around 7 centimetres (3 in), but the fish can grow up to 10 centimetres (4 in) under excellent conditions, especially if brought to the end of its life expectancy, around 6 years. It possesses a parietal eye which permits it to see prey insects and predators above it on the surface. A. lineatus can jump very well.
Pachypanchax playfairii, the golden panchax, is a species of Aplocheilid killifish, the only species of freshwater fish endemic to the Seychelles, a group of islands in the Indian Ocean, east of Tanzania. It is the only member of its genus found outside of Madagascar. Within the Seychelles it is found only on the granitic islands. Here it occurs in small freshwater and brackish water streams, feeding on worms, crustaceans, insects and fish. An egg scatterer, the golden panchax breeds amongst floating water plants. This species is unusual in that the scales of the male become lifted during the breeding season, giving the skin a rough appearance. Unlike the true annual killifish, they live as long as similar fishes, a few years, 3 years is not uncommon 5 is unknown.
Pachypanchax omalonotus, the powder-blue panchax, is a species of Aplocheilid killifish endemic to Madagascar where it is found on the island of Nosy Be and in the Sambirano River basin and adjacent streams on the mainland. Its natural habitat is rivers.
The clown killi or banded panchax, is a species of fish in the family Nothobranchiidae, an African rivuline, native to fresh water habitats in Guinea, Liberia and Sierra Leone in West Africa.
White Spot is a Canadian restaurant chain.
The whitespot hawkfish, the halfspotted hawkfish, multicolored hand-fish and ornate hawkfish, is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is found in the Indo-Pacific region.
The Ceylon killifish is a species of killifish endemic to Sri Lanka. This species grows to a length of 9 cm (3.5 in). Males and females have a black dot at the rear end of the base of the dorsal fin. The females lay 50–150 eggs. The specific name of this fish honours the Inspector-General of Fisheries in India Francis Day (1829-1889), who first reported this fish, although he identified it as Aplocheilus panchax.
Epiplatys sexfasciatus or six-barred panchax is a species of fish in the family Aplocheilidae that can be found in West and Central Africa. The fish is a timid surface dwelling predator. The six-barred panchax is up to 10 cm (4 in) long and closely resembles Epiplatys longiventralis.
Oryzias curvinotus, or the Hainan medaka, is a species of ricefish which is found in Quang Ninh Province in northern Vietnam and Hainan, Guangdong and Hong Kong in southern China. It is found in both fresh and brackish water. This species was described as Aplocheilus curvinotus in 1927 by J.T. Nichols and C.H. Pope with the type locality given as Nodoa, Hainan Island, China.
Fundulopanchax is a genus of killifish living in near-coastal fresh water streams and lakes in Western Africa. All species were previously biologically classified as members of the genus Aphyosemion, with the exception of Fundulopanchax avichang, F. gresensi and F. kamdemi, which were all scientifically described after the major revision of the Aphyosemion complex.
Aphyosemion australe, the lyretail panchax, golden panchax or Cape Lopez lyretail, is a species of freshwater fish belonging to the family Aplocheilidae. It is found around Cape Lopez and in surrounding areas in Gabon.
The frail gourami or noble gourami is a mouth brooding species of gourami native to northeastern India and Bangladesh. This species grows to a length of 10 cm (3.9 in). It is only seldom found in the aquarium trade, courtesy of its extreme sensitivity to shipping stress and high levels of aggression. This species is the only known member of its genus.
Aplocheilus parvus, the dwarf panchax, is a species of killifish native to India and Sri Lanka. This species grows to a length of 6.3 cm (2.5 in). Its natural habitats are sheltered fresh and brackish water tanks, small streams and rivulets overgrown with vegetation. They are rarely use as an aquarium fish. It is often misidentified as Aplocheilus panchax or as Aplocheilus blockii.
Scarus forsteni, commonly known as the whitespot parrotfish, or Forsten's parrotfish, is a marine fish native to tropical areas in the western Pacific Ocean, where it lives in coral reefs and feeds on benthic algae.
The dadio is a cyprinid fish, is rarely seen in the aquarist hobby but is not entirely unlike the Danio nigrofasciatus in appearance. Laubuka dadiburjori is a gold/silver fish with a blue line, it has two colour morphs, one with a distinct blue line, the other with a dotted blue line. Barbels are not present. Like most danionins, this fish has a tendency to jump. A tight fitting lid with no gaps is recommended. Endemic in India, where both colour morphs co-exist, the fish is found from Tamil Nadu to Goa. It is necessary to avoid making it coexist with big fish which would only make a mouthful of it.
Genarchopsis goppo is a species of a trematode, or fluke worm, in the family Derogenidae.
The whitespot ghost shark is a chimaera species in the family Chimaeridae, which lives in parts of the Galápagos Islands in the southeast Pacific Ocean. It lives in waters with steep slopes and boulders and grows to a total length of around 40–50 cm (16–20 in).
Aplocheilus blockii or the green panchax is a species of fish native to waters around India, Sri Lanka, and Pakistan.
Aplocheilus kirchmayeri is a species of killifish native to India. It was named after the aquarist J. Kirchmayer. Its validity as a species has been questioned, with some experts believing that it is a subspecies of Aplocheilus blockii. The species has been noted to be rather difficult to keep in an aquarium.
