So I posted this in the hitchikers forum but I might as well add it to my thread too.
I traded in a large piece of LR last night for some smaller pieces. 2 of the pieces had some decent size holes in them which I assume this guy was hiding. I am pretty sure its a pest most likely majano but its quite large. 2-1/2" across tenticals at least 2" long.
Here are the pics of it and my left side of tank reaquascaped for more coral placement. And a FTS too.
Believe it or not its a rose color with flourescent green tips.
