Often observed to be cleaned by cleaner wrasses, and how the body color changes from silver to black during cleaning.

With more than 3000 different species all over the world, with sizes ranging from small rice grains to 30cm ones! This variety, colorfulness, and slow movement make them a popular creature especially for macro lovers and photographers. Can be seen all year round, but there are more types that can be seen in winter.


No. 10 Anthias

Anthias are mostly small, but thy form complex social structures based on the number of males and females and also their position on the reef itself.


Anthias do school in huge groups, though they tend toward more intimate subdivisions within the school, appropriately called “harems”. These consist of one dominant, colorful male, and two to 12 females — which have their own hierarchy among them — and up to two ‘subdominant’ males, often less brightly colored and not territorial.


Within the swarm of females, territorial males perform acrobatic U-swim displays and vigorously defend an area of the reef and its associated harem. All Anthias are born female; if a dominant male perishes, the largest female of the group will often change into a male to take its place.


The Yaeyama Islands are home for Redfin, Scalefin, Purple, Stocky and Square-Spot Anthias. They can be found on all Islands throughout the year.
