}}Aphyocypris lini, the garnet minnow or Venus minnow, is a species of cyprinid endemic to China.[1] It was first collected from Hong Kong by A.W. Herre in 1936. The introduction of mosquitofish (Gambusia affinis) and habitat destruction caused the extirpation of this species from Hong Kong and the species was considered to be extinct in the wild. However, a similar species Aphyocypris pulchrilineata was discovered in Guangxi in southern China, but this species lacks the dark spot on the base of the caudal fin.[2] DescriptionAphyocypris lini is a small fish which has a yellowish-brown body with a bluish back and a white underside which are separated by a series of parallel stripes with the middle stripe being reddish-yellow, a bluish black stripe above and an iridescent green line below it. There is a large blue spot, edged with gold at the base of the caudal fin while the fins are white. It has pelvic scutes which run from the base of the pelvic fin to the anus. There is no lateral line but there are 30–32 scales along lateral axis. Adults grow to 50 mm total length.[3] It has three spines and seven soft rays in the dorsal fin with three spines and eight soft rayes in the anal fin[4]DistributionThis species is endemic to southern China and it was first recorded in Fanling in the New Territories of Hong Kong in 1939, and was found in the Tai Mo Shan area in 1992, but since then there have been no records in the wild.[3] HabitatAphyocypris lini is a benthopelagic fish species which lives ditches and rivers where there is clear, shallow water with dense aquatic vegetation. Spawning occurs in open water with sandy and gravel subsrates.[3]ConservationThe decline In the wild populations of Aphyocypris lini is thought to be due to habitat destruction by human development such as the construction of hydroelectric projects, water pollution and deforestation. They were possbli also affected by competition from introduced fish species such as the mosquitofish. The only currently know population of the garnet minnow are in captive breeding facilities in Hong Kong, Macau and some other southeastern Asia countries where they are bred for export in the aquarium trade. It is possible that the species could be reintroduced to the wild using captive bred fish after habitat restoration and the removal of invasive alien competitors.[3] Sources1. ^{{cite web|title=ITIS Standard Report Page: Aphyocypris lini|url=https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=688415#null|website=www.itis.gov|accessdate=30 September 2017}} {{Taxonbar|from=Q3760614}}2. ^{{cite web|title=[Ichthyology • 2013] Aphyocypris pulchrilineata • a new miniature cyprinid species (Cypriniformes: Cyprinidae) from Guangxi, China | url = https://novataxa.blogspot.co.uk/2013/03/aphyocypris-pulchrilineata.html?m=1 | accessdate = 11 December 2017 | publisher = pskhun | work = Species New to Science | date = 20 March 2013}} 3. ^1 2 3 {{cite journal | author1 = Menghong Hu | author2 = Youji Wang | author3 = Siu Gin Cheung | author4 = Paul K.
