I have a Nebulous Wrasse. I can tell you a lot about them. It is the reason I made my 75g into an aggressive tank.
Speaking from my experience with a Nebulous Wrasse, they are an amazing Wrasse if you don't mind the aggressiveness towards other Wrasses.
I can't keep other wrasse with it, they will fight to the death.
It spends most of its time picking at rocks, eating any little hitchhiker it sees, it does eat snails and some clean up crews. It's a nasty predator to your cuc.
If you get em small and you have shrimps like cleaner shrimps...everything will be fine but one day when it's bigger.....he will eat them.
In the beginning it was the king of my reef until I started adding other fishes such as a hamlet which it holds its ground against but now sometimes swims away from.
I added a Sailfin Desjardin and that became the king of the reef and the Nebulous slowly started realizing there are much bigger fish in its reef. It avoids problems now most of the time.
It also is a master at hiding for up to 2 months at times , specially when it's scared. It gets scared when u start doing tank stuff so it hides in the sand.
Unless u know for a fact that u killed it somehow, never count it out. Mine has slept for over 2 months and suddenly pops out of nowhere like nothing ever happened.
Anyways, this is my experiences with a Nebulous Wrasse. It's my fave Wrasse for the last few years. This is a picture of him. I call him Rocky.
