Occurs in shallow creeks with sandy-muddy substrate rich in plant debris. Rarely found in principal river beds (Ref. 27188). Although not abundant, it appears to be well-adapted to its environment as evidenced by its leopard outfit which enables it to camouflage itself. The isolated captures suggest a solitary existence. Unlike the Tatia which lives mostly in estuaries, G. leopardum appears to live mainly in the upstream portion of rivers (Ref. 35381).
