Wrasse - Sandagers Wrasse

Coris sandeyeri, Sandager's wrasse, is a species of wrasse native to the southwestern Pacific Ocean from Australia to New Zealand and the Kermadec Islands. This species can be found on reefs down to depths of about 60 metres (200 ft). It can reach a length of 25 centimetres (9.8 in) TL. It can also be found in the aquarium trade.The wrasses live in small shoals consisting of one male and several 'attendant' females and juveniles. In the presence of the male, all juveniles will grow into females, but when the male dies or is removed from the shoal, the group's dominant female then undergoes physiological changes to convert herself into a male.
