Stays in schools of several dozens of individuals (Ref. 35381). Occurs in creeks with sandy bottoms with slow or strong current (Ref. 27188). Swims mostly in backwaters and hides itself under logs or rocks. Its 'locking' mechanism built with its bony plaques, which permit it to keep three spines erected, is a good passive defense mechanism. Lifespan can last for 7 years. (Ref. 35381).
