Description: The Naval Institute conducted top secret analysis in "Subaqueous" - an underwater lab located on the campus of Mount Promontory. Unbeknownst to the scientists, the fish gained strength during this scientific experimentation and decided to revolt against the scientists. The lab was completely destroyed during the rebellion; however, several mysterious fish sightings occur to this very day.

To unlock Subaqueous, catch a Nuclear Arms Squid Fish in Hexperiment. After being submerged mid-wrangle you discover this secret underwater area. Like its Farovian counterpart in Misty Cliffs, be prepared to spend some time on this, as the Nuclear Arms Squid Fish is classed as "possibly extinct". Use of RLC/FLC and/or Liquid Gold is recommended or have patience -- some wranglers have cast 50+ times before catching their first Nuclear Arms Squid.
What to catchEdit
A rogues gallery of each Subaqueous fish can be found in The Fish of Subaqueous.
