Description
The Inland Riffle Sculpin is a small, bottom-dwelling freshwater fish native to the Pacific Northwest, characterized by its broad head, large pectoral fins, and mottled camouflage. This predatory species thrives in cool, highly oxygenated, fast-flowing waters where it ambushes aquatic invertebrates. Due to its specific environmental requirements, it is considered an advanced species for aquarists.
