Thanks nu-nu, always worrying about my tanks. I havent seen the wrasse that I put in the 75 yet either. But, when I saw him at the LFS, he was under the sand. I am paranoid and continue to look around the tank to see if he jumped. I am going through all my aquarium stuff in the garage to see if I have the covers for that tank.
EDIT: As soon as I posted I went out and looked at the 75 and the wrasse is out swimming around! Very relieved, and the nem is working his way back to the top of the rock! I guess I worry for nothing!
