Aphanius mento


Aphanius mento
Black Persian Minnow
蓝珍珠沙漠鱂鱼
This species has something of a confused history having been previously been considered synonymous with both A. sophiae (a separate species native to Iraq and Iran) and A. cypris (currently considered a junior synonym of Aphanius mento). Although some populations occur close to and even sympatric with other members of the genus in Turkey phylogenetic studies have shown it to be more closely-related to the Middle Eastern species A. dispar dispar, A. d. richardsoni, A. ginaonis and A. sirhani . It's considered to be one of the more ancient species of Aphanius having diverged from the ancestor of the A. dispar group between 25 - 28 million years ago and is arguably the most attractive so has found greater popularity in the hobby than its relatives. 


本种是鳉鱼中少数生活在弱碱性水质的鱼种,它们的色彩特殊,各鳍上有漂亮的白色斑点,相当耀眼可爱。沙漠蓝珍珠鳉体质强健易饲,雄性间畅游争斗现象,但一度水族认为基本上还是适合与其他弱碱性水质的中小型鱼类混养。
