Info
The bullhead is an all-rounder, living in fresh water, brackish water, and sea water, tolerating a salinity of almost 0 to about 30 psu and a water temperature range of 4° to 27° Celsius, with egg laying occurring in cold water at 4°-5° Celsius.
The carnivorous bullhead is a carnivorous, catadromous fish that feeds on a variety of different copepods in its juvenile phase, see https://www.fishbase.se/TrophicEco/FoodItemsList.php?vstockcode=41163&genus=Trachidermus&species=fasciatus
Since adult animals also eat fish and shrimp, enthusiasts should keep the animal in a pure fish aquarium, or better still, admire it in public display aquariums or in nature.
Trachidermus fasciatus has three vertical, dark brown bands on its upper body and/or narrow, brown cross bands on its pectoral, dorsal, anal, and caudal fins.
