I have that jawfish.
Pts to note:
If you wanna keep a nice sandbed. place mushrooms, yumas, rics on it, then dun get this fella.
This fella dig trenches all over my sandbed - spouting the sand all over my corals.
Else, it is really a very nice fish and very interesting to watch and the positive thing is that you do not get algae growing on your sandbed.
Also get Sam/ Peter to feed them pellets and choose the most greedy one.
You will need to supplement with mysis/ frozen food though.
