Aggressive Melenarus

[MattinIdaho]

I just got a male and female pair of Melenarus Wrasse for my 120 on Wednesday. Male acclimated very well from the beginning and has always been active and eaten well. Last night he started swimming aggressively into the glass of the tank. He was fine this morning for about an hour but has since been doing it for 4 or 5 hours. He is colored up nice and attacks the same spot. I am guessing he is seeing his reflection and is being aggressive towards it.
Any ideas of anything I could do. He is hitting the glass hard enough to hurt himself I am afraid. He does not pay any attention to the female or any of the other fish (5 chromis and Coral Angel).

If it's only one area you can tape a piece of white paper on the outside of the tank at that location for a while. That'll stop him from seeing his reflection there.

That finally dawned on me and I tried it but he just moved from the side to the front corner. I'm interested to see if he is still doing it today. He eats like a pig when I feed so I don't think there is anything wrong with him.
