TBS Founder, “Photo shows the filter feeder mechanism that TBS barnacles use to filter food from the water. These little guys are hard to keep alive, but if you dose with liquid food these guys can survive and even thrive on your rock.”

Small, calciferous purple mountains that are either empty caverns or house a creature that sweeps the water column are sometimes found on vintage live rock.

These peaceful filter feeders require a well-fed tank, oyster eggs and phytoplankton.
