Description
The Knobfin Sculpin (Jordania zonope) is a small, camouflaged marine fish native to the rocky shores of the Eastern Pacific. It is a bottom-dwelling predator, using its mottled coloration to ambush small crustaceans and invertebrates. This species requires a coldwater marine setup, making it an intermediate to advanced species for dedicated aquarists.
