Agreed, I didn't know there was a mandarin going back in the tank. The wrasse will compete for food. You might be able to get a wrasse out of the Halichoeres family. I will have to do some research to see if they will compete as well. I know my Chrisymas wrasse would follow me around the tak when I used the scraper or mag float - he would love it when I disturbed the sand and then dive in for for what ever was uncovered. What I like about the wrasses is the fact that as far as I know I never had any pest issues w/ my coral.
