Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Occurs in the rocky habitat, preferring areas of rocks mixed with sandy bottoms. It occurs in the shallow water (0.5–6 m depth) but has on occasions been observed at 20 m or more. This species remains very close to the substrate, trying to keep in close contact with the rock surface with its belly (in trying to do so, it sometimes swims upside down). This species leads a reserved, secretive life and it seems to be weakly territorial.
Systems:	Freshwater
