South-African reef New member May 28, 2011 #1 It was fine last night this morning It was looking like this.
MMreef Active member May 28, 2011 #3 RTN- rapid tissue necrosis. You need to cut off this branch in order to have chance to save rest of this coral.It spreads fast so don't wait.As far as reason for it ,could be different things,most likely swing in water parameters.

poidog Active member May 28, 2011 #4 cut the healthy branch off now and mount it to a plug. the rest will most likely die.
MMreef Active member May 28, 2011 #8 Not necessarily,I've seen RTN even in mature tanks,it happens sometime seems for no reason.
