Description
The Cantor's Gudgeon (*Oxyeleotris urophthalmus*) is a predatory fish native to Southeast Asia, characterized by its mottled brown camouflage and an eyespot on its caudal fin. Growing up to 12 inches, it requires a large aquarium and is best kept in a species-specific tank or with very robust, similarly sized tankmates. This adaptable species thrives in slow-moving freshwater to brackish environments.
