The size of this fish averages at around 12 to 22 cm. They are often spotted around the beautiful coral reefs and are loved for their stripy colours. If you take a night dive, the butterfly fish can be spotted hiding amongst crevices in the reef, and if you observe them closely it is noticeable the fish has changed its colourations. If a night dive sounds exotic, check with your Maldives resort for in-house tours or the contact details of the nearest tour operator.
