The only drawback to the Grox is their aggressive and vicious temperament. They will usually charge any creature on sight, including other Grox. They are also large, fast and dangerous beasts, about five meters long and well-muscled. They are territorial and like their privacy, so attempting to herd Grox together would easily drive them into a rage. The solution used is to lobotomize most of the stock while keeping the breeding animals suppressed with electro-pulsers wired directly into their small brains. Even with these precautions accidents still happen, and Grox are usually kept on agri worlds and isolated from human settlements.
