I'ts been a week to the day that I have had my 14" gigas. It acclimated fine and has been open until last night he closed up about 75% of the way and has not opened yet. I have notice my foxface nipping at him (he has never done it to any of my other clams ever). Just wondering if anyone has any ideas I'm trying to remove the foxface now but I have been unsuccesfull at that. I have a 120g tank with about 225lbs of rock and do not want to take it apart. I'm on my last nerve with this damn foxface.
