Description
The Bighead Goby (*Ponticola kessleri*) is a bottom-dwelling fish characterized by its large head and mottled brown camouflage, allowing it to blend seamlessly with sandy or rocky substrates. Native to the Ponto-Caspian region, this territorial carnivore prefers cooler, slightly alkaline freshwater to brackish environments. It can be aggressive towards smaller fish and conspecifics, requiring careful tankmate selection.
