I have a green wrasse, just the regular lime green one. He stays hidden quite a bit and can also hide in the sand. In fact when I moved tanks as I was scooping through the sand for critters I scooped him up. He doesn't fight with any of my other fish, yellow tang, blue hippo, clown, royal gramma, valentini puffer, yellow clown. I did have a 6 line wrasse and he was after everything. This one is so much less aggressive. He's a cool looking fish. Hope this helps.
