I'm debating pulling my LM out when I upgrade to the larger tank. He doesn't eat much in the way of algae anymore, since he has decided he likes a more meaty diet and actively goes after the mysis or live brine and feeder shrimp. He does totally ignore my green spotted mandarin, but he absolutely hates my fork tail blenny. I regularly see him chasing the fork tail off when he sees him near the rock. When he isn't doing that he's perching on various Zoa colonies or some of my mushrooms and "dances" at the front center of the tank. He manages to push almost all the sand back to the middle of the tank and I have to go back behind him and shift it back. It doesn't matter if I put smallish rocks there to block him, he wiggles down between them and the glass and managed to push the rocks back away. He has even nipped my fingers a few times when I go to move the rock and sand back after he has moved them. He is the single most annoying fish I have now.
