Bill Addison, legendary founder of the C-Quest farm in Puerto Rico, coined the term Gladiator when describing a variety of clownfish he discovered in his hatchery. We imagine that Bill must have encountered uniquely patterned specimens in a batch of Amphiprion ocellaris that displayed head patterns reminiscent of a helmet. As luck would have it, Gladiator genetics were inheritable and Bill created a bloodline of this variety. It seems that not all Gladiator specimens exhibit the warrior helmet pattern; most only possess bars that are noticeably wider than their Gladiator-gene-lacking brethren. Other Gladiators exhibit swirls, connecting bars, or white patterns not found on wild-type specimens.
