Jawfish

Comical, entertaining, and peaceful, Jawfish make a great addition to any saltwater community or reef aquarium. They will construct a burrow in aquarium substrate. Jawfish prefer to keep an eye on everything going on and will often build the burrow in the center of the aquarium. They will typically spit gravel at any fish that comes too near to the burrow (and even at the hobbyist who tries to get a closer look).
