Without going into much detail does anyone know what this is? It starts at the base of my acros and eventually the entire colony dies, takes weeks to months but once I see this the colony eventually dies. Any idea?
The recession you see has taken about a month since I noticed it at the very base of the coral as a super thin strip.
