Distribution And Background

Brown Clownfish or Brown Saddleback Clownfish a member of small group of three anemonefish known as the “Saddleback Complex” that has scientific name is Amphiprion polymnus. Depending on where they are found and the anemone they inhabit, different color varieties exist. Overall, their color can range from yellowish orange, black, or a light brown shade, and they will have a tailfin which is white-edged. The pectoral fins and the nose can also differ in colors, and may be orange, white, or brown. Nevertheless, all the color variations have a wide white headband and a wide white middle band that looks as if it forms a saddle shape.

Located from Malaysia through the Solomon Islands, then northwards to the Ryukus and then southwards to Australia, Western Pacific.

They can be hosted by the Haddon’s Carpet Anemone Stichodactyla haddoni, sometimes by the Leathery or Sebae Anemone Heteractis crispa, and on rare occasion by the Long Tentacle Anemone Macrodactyla doreensis.

The Saddleback Complex is relatively rare and may not be as well suited for captivity as the other species. Acclimating them to captivity usually takes about three months, and after that they begin to begin to exhibit less panic. It is believed that they do reasonably well once acclimated to captivity, and some have even spawned in captivity.

Brown Clownfish – Description

In this clownfish, the body is light brown to dark brown with an orange face. Their body shape is much sleeker and more oval in shape, similar to both the Sebae and Latezonatus clown fish. As can be seen from this picture, the saddle starts behind the dorsal fin of the fish, and curves forwards and down across the body of the fish, usually ending only part way down. In addition, the tailfins, which are usually dark, are typically accompanied by white edges around.

General Size Specifications: 

The Brown Saddle Clownfish generally grows up to five inches in length. Generally, the smaller sizes range from ¾ to 1¼ inches;; the medium sizes range from 1¼ to 2½ inches; and the largest sizes range from 2½ to 4 inches.


Saddleback clownfish are considered semi-aggressive, but are among the most peaceful of clownfish. Saddlebacks are generally peaceful members of the tank, and they will not bother their tankmates. It is believed that these clownfish are more tolerant of other clownfish in the wild, due to the fact that they live in groups. They can be kept in the same aquarium with most peaceful, non aggressive fish, with the exception of those that are large enough to swallow them.

Foods And Feeding

This species of clownfish is omnivorous, like other clownfish, and therefore should be fed as such. A few of the excellent choices are meaty, enriched foods, such as mysis shrimps, spirulina brine shrimps, and chopped table shrimps, as well as herbivore preparations. You should also feed the fish flakes and pellets with Spirulina added if there are not enough algae for them to feed on in the tank.

You should feed adults twice a day, and juveniles three to four times a day, whatever they will consume within three minutes. 

Aquarium Care

As one of the largest clownfish varieties, it is recommended that this fish be kept in a tank no less than 30 gallons in which there is plenty of room for the fish to hide and swim. Small groups are preferred, and anemones like Haddon’s Sea Anemone Stichodactyla haddoni, which is a host anemone, will make an aquarium more successful. Aging increases its aggression towards conspecifics.

Tanks that are well maintained and provide accessible water are beneficial to them. If the water quality is poor for an extended period of time, they will become ill and also contract diseases.

Females tend to have a yellow face and all are larger than the males. Males tend to have brown faces in most color morphs.

Are Brown clownfish easy to Keep?

I cannot say that keeping this fish is easy, but it is not impossible either. As a less durable species of clownfish, saddleback clownfish are recommended to intermediate to advanced aquarists. Generally, they have a hard time adapting to their new surroundings, and have been known to run into the glass or jump out of the tank if they are feeling threatened. However, once they get used to captivity, they tend to do well. The process of becoming accustomed to captivity can take three months.

Can Saddleback be kept with Percula Clownfish?

The Saddleback can be kept with other mellow clownfish such as the True Percula Clownfish. In this aquarium, two anemones can be kept together with two species of clownfish, each of which is kept as well. The tank that you choose should be at least 75 gallons in size or bigger, depending on the species of anemone you choose to keep.
