The Gladiator Ocellaris Clownfish has a very sleek stripe pattern which contrasts with its vibrant orange. Its smooth wavy white stripes come from its Gladiator or Wyoming White parent and the pattern will vary, making each clownfish unique. Their designs can make it seem as if they are wearing a roman-era helmet, which leads to their common name "gladiator".

The Gladiator Ocellaris is a designer clownfish that will do well in a reef environment - they are best housed in pairs, though they can be kept in harems with enough space. This clownfish does not need an Anemone to survive, but will accept many different Anemones as its host, including corals. Their favorite Anemones to call home are the Carpet Anemones Stichodactyla Gigantea or the Magnificent Anemone Heteractis Magnifica.

These fish will accept most fish foods and are perfect for reef tanks. More than one can be kept in the same aquarium and they prefer to be kept in groups.

Clownfish have a very distinct swimming motion that is different from most fish. This is likely passed on through their genetic makeup from centuries of wiggling within the tentacles of Anemones. As the Clownfish wiggles within the stinging tentacles the Anemone's mucus is likely smeared over the Clownfish's body, which then protects it from additional stings.

 In the wild they live in small groups with one large dominant female, one smaller sexually active male, and a handful of smaller males and juveniles. When the female is lost the largest male will then change sex and become the dominant female with the other Clowns moving up the ladder behind it.
