I guess I have been in denial since I found one of my emerald crabs claw, and seem to be one emerald short. Ok, now one of my clams took it in the gland, and died today. On top of all of this, I have not seen my peppermint shrimp in 3 days. I have stayed up late the last three nights, with a red filter on my flash light and nothing. I haven't seen any predatory crbs or shrimp. My hermit population has also slowly declined. I am at an impass. I don't want to tear into my tank w/o knowing what I'm looking for. My cleaners, 1 emerald and fish are still alive. Does anyone have any suggestions? Should I just rip into the tank not knowing which hole it, whatever it is...lurking. Need some advice, please help!
