Blue Barnacles are a type of Flora found exclusively in the Primary Containment Facility Aquarium.
There are barnacles found on Reefbacks that share a model with the singular Blue Barnacles. These act similarly to Limestone Outcrops.
The Blue Barnacles resemble clusters of real life Barnacles, embedded in a calcified, dark gray base. They have a maw with a light turquoise bioluminescent glow.
Blue Barnacles come as Blue Barnacle Clusters, and singular Blue Barnacles.
