I've seen them all different colours and sizes and shapes but this one in my tank just grew another head!! The shell measures about 11" long and the larger of the crown measures about 3" wide whilst the smaller one measures about 2". Feeds on photoplankton. Add coral food (comes in a liquid bottle) to keep the worm alive. Will not survive in temperatures above 29" or will starve to death if not fed. Not for the beginner.
Sorry about the Mandarin. He loves the limelight. Very brave and cheerful fat fella he is.
