Description: Sig ran an illegal diamond lab in Sans Culpra which supplied his lovely ladies with top of the line jewelry. Unfortunately, the Rock Fish sampled Sig's carbon-based chemical which created the Diamond Rock Fish. Too heavy to swim, the Diamond Rock Fish attracts other species by releasing a haunting aroma from its tongues. Notes:How to catch Diamond Rock Fish: Catch Diamond Rock Fish by using a Level 54+ Algaenite or Planktonite in Sig's Wasteland. Requires the skill of Sub-Zero Survival Training. First (non-Sans Culpra/pure) Blue Crescent fish to get mutated - from the Rock Fish.
