How big is your tank?
the 4line and 6 line stay small but can get mean at times. Mine killed a clown. I htink it sensed weakness or soemthing. The clown got beat up a few times by another clown before. That said the wrasse doesn't look twice at my
royal gramma.
Looking back I may have avoided this guy in exchange for some more peaceful wrasse.
There's lots to chose from. Take a look at the fairy and flashers. I like the banded
possum wrasse too. The only thing with the flashers is that I hear if you only have one its colours will fade overtime.
But then again the lined guys are super active and great to watch. They hunt the rocks all day long.
well HTH somewhat
goodluck
what other fish do you have/plan to get?
