If the pressure in the habitat is increased, then the anglerfish will have a (higher/lower) health rating.

The anglerfish will exhibit healthy health rating.

The anglerfish refers to a bony fish named after its featured mode of predation. The species of the fish occur globally, most of the anglerfish are benthic, that is, they dwell close to the floor of the sea. At the depth of deep-sea, the pressure is very high, however, various creatures exhibit no issue living there.

In the absence of gas-filled spaces like swim bladder or lungs, the species in the great deep sea are less influenced by the pressure than one can think. Though the species adapted to such pressure conditions, when being brought to the surface of the sea may encounter with certain metabolic issues. Thus, increasing the pressure will cause no harm to the health of anglerfish.
