Hi,
I am fairly new to reef aquariums. My tank is 4 months old, with one fish and a few coral.
I noticed this line on my Duncan today, with what looks like some clusters of spots on the line. See photo.
It has been doing well in general, normally open and extended, but some times closes up at night.
Any thoughts?
TIA
