The Scad Fish is a Tier 4 ship in the Nautic Series mod. It rapidly fires a single, medium damage laser from the front. The lasers fired by this ship have a very high velocity, making them hard to dodge.
However, the energy regen is poor for mining, making it recommended to stay Archerfish and skip to Reef Shark, unless you have Mining pods.
This is the first ship of the "killer branch": Scad Fish > Reef Shark > Shark or Grouper Fish.
