Description
The European Bullhead is a bottom-dwelling, coldwater fish native to clear, oxygenated rivers and streams across Europe. It is characterized by its large head, broad pectoral fins, and mottled camouflage coloration. This territorial carnivore preys on aquatic invertebrates and small fish, making it a fascinating but specialized aquarium inhabitant.
