Also called the Moustache Jawfish. The Black Cap Jawfish are interesting animals with an amusing defense mechanism. When threatened, jawfish will open their mouths to comical proportions in an attempt to intimidate. Provide a loose substrate as the Black Cap Jawfish constructs a burrow to use as its home. This fish can be high strung until they settle into an aquarium. Not aggressive, but will defend its burrow. Diet should include mysis and brine shrimp, as well as other small chopped frozen seafoods.
