Sebae Clownfish do very well in aquariums of 30 gallons or larger with or without the presence of an anemone. Ideally they should be provided with live rock to provide the territory and shelter when they feel threatened. Also, while the presence of an anemone is not mandatory, they are appreciated and will help the Sebae Clown feel more at home within the aquarium environment. Sebae Clowns are one of the larger and more territorial clownfish species, thus they should be kept as the only clown in smaller aquariums or in a mated pair or small group in larger aquariums. When kept in a group, the Sebae Clownfish will establish a hierarchy where the largest specimen will become the female, second largest the dominant male and the rest of the group will remain juveniles. The process of establishing their group hierarchy can be stressful on all the fish involved, so it is recommended to keep a pair of one large specimen and one small specimen, so they will have the best chance to pair off with little to no aggression. When pairing up the Sebae Clown with a host anemone, the following anemones are the most compatible: Sebae anemone, Long Tentacle anemone, Ritteri (Maroon) anemone, Carpet anemone, Saddle anemone, Bubble anemone.
The Sebae Clown is probably one of the easiest captive marine fish species to feed, as they will eat a large variety of meaty or vegetable based foodstuffs including all the commonly available flake, frozen and freeze-dried preparations commonly available within the hobby. The Sebae Clownfish should be fed a diet that includes a variety of meaty food items such as brine shrimp, mysis shrimp, marine flake, chopped marine foods and carnivore or herbivore frozen preparations.
