I'm planning on setting up my 29 gal. tank to be as self-ran as possible. I take a lot of business trips out of state and am often gone for a few days at a time. I plan to set up an aquafuge to help lower nitrates and work as a natural food supply for the fish and possibly corals. I'm going to replace the contents of my cannister filter with LR rubble. I also plan to have a very efficient clean-up crew. The one thing I'm still not sure about is what if something dies while I'm gone. If a snail, crab, fish, or something died in the tank and I was not here to remove it, would the clean-up crew eat/dispose of it?
