Well, two of the Jawfish have been MIA for 2 days, but today I see a third one. He is not in good condition. He has lost the bottom portion of his jaw, and he is quite stressed. I'm not sure what happened to him, and I'm not sure he is going to make it.
Albertan: My sand bed is 75% Caribsea Select, and 25% Caribsea Super Reef. It is 3-4" on each end of the tank where my rocks are laid out for good borrow building, and the center of the tank only has 1/2-1". I used live rock rubble to build small barriers to hold the sand up nice and deep on the ends.
