..non si sa nulla della riproduzione in cattività... neppure su quella in natura.. almeno da quanto riporta "Seriously fish"...
sono pesci che necessitano, per avere condizioni ideali 18°... a 22° iniziano a soffrire... CI VUOLE UN REFRIGERATORE essendo i pesci diffusi in un habitat che va dai 900 metri sul livello del mare in sù..
..praticamente TUTTO il web racconta della necessità di proteggere le specie a rischio endemiche della Cina e del sud est asiatico, in quanto NON esistono praticamente norme protezionistiche ( a differenza del Brasile e del SudAmerica dove si cerca di far rispettare molte restrizioni)
fate quello che volete.. importateli, teneteli, cercate di riprodurli, tentate di motivarlo... ma come cittadino del mondo e da ex- moderatore di questo Portale (commerciale).. mi sento in dovere di riportare solo una minima parte di questi articoli.. basta cercare Protomyzon e in OGNI articolo esiste la parola "endangered" e "restricted area"....

"Officially known only from a handful of headwater tributary streams draining the Dayao Mountain (Dayaoshan) in Jinxiu County, Guangxi Zhuang Autonomous Region, southern China.
There are just three confirmed localities of which two drain into the Liu River (Liujiang) and one the Gui River (Guijiang), themselves both north bank tributaries of the much larger Pearl River (Zhujiang) system.
It remains unclear if the fish in the aquarium trade are collected from one of the above, one of which lies within a protected forest park, or there exist undisclosed, additional locations though the latter possibility appears likely (Z. Hang, pers. comm.).
The IUCN currently list it as ‘Least Concern’ but a report by Kong et al. (2008) suggests the overall population to be small and habitats under threat of degradation from dam construction, loss of water quality and the use of electrofishing and ichthyotoxins."

"This pattern changes drastically as the fish mature, breaking up and taking on a much less striking, but still attractive mottled brown/cream appearance. A dark band often forms along the lateral line.
Notes: P. pachychilus is listed as of ‘least concern’ on the IUCN red list of endangered species, but ‘rare’ in the China Red Book of Endangered Animals and ‘vulnerable’ on the China species red list.
The main threats come from habitat degradation, including deterioration of water quality due to pollution, construction of hydropower dams, electro-fishing and seasonal changes such as severe desiccation of some of the waterways.
One population that lives in the Buquanhe river remains inside the protected area of the Dayaoshan National Nature Reserve in China, but other populations living outside are at risk."

ps. scusami Entropy... grazie per l'intervento, decisamente preparato, rispetto a ciò che avevano risposto precedentemente i tuoi colleghi... sono pienamente d'accordo in quello che scrivi, ma aggiungo che la severità, per quanto riguarda un Portale, in questi casi debba essere maggiore... a presto!
