The blue hanging can grow up to about 15cm. Next, let's take a look at other information about the blue hanging!

The blue hanging inhabits the reefs and flat waters that are clear, facing the sea and passing by the tide. The fish usually gather in the water layer 1 to 2 meters above the bottom of the sea. The juvenile blue or blue juveniles gather near the staghorn coral headland. Once frightened, they immediately hide among the branches and buds of the coral. Blue hangings mainly feed on zooplankton and sometimes algae.
