Amphiprion frenatus

Brevoort, 1856

Tomato Anemonefish, Tomato Clown

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Gulf of Thailand east to Palau, northwards to Japan, and south to Java.

Size: 5 inches (14 cm)

Natural Environment: Inhabits lagoon reefs and protected reef faces at depths between 3 to about 40 feet (1 – 12 m) and usually found inhabiting only the Entacmaea quadricolor anemone where it feeds mainly on planktonic crustaceans (copepods, mysis, and shrimp larvae), and filamentous algae.

General Husbandry: Often available in the trade, with this quite hardy species adults having a bright orange head with a white vertical band just aft of the head, and the remaining body blackish. Juveniles retain the white vertical band, yet are orange throughout the body and head.

Best maintained in aquaria having live rock, hiding places, macroalgae, and semi-aggressive tankmates.

As to diet, will eat most regular aquarium foods, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam, etc., and plant material, e.g., flake foods, especially those containing Spirulina and should be offered once or twice daily.


    Order: Perciformes

    Suborder: Labroidei

    Family: Pomacentridae

    Genus: Amphiprion

FYI: In the wild, its hosting anemone is only the Entacmaea quadricolor.

Maintain only as a single specimen, or as a mated pair.

Do not house with other species in this family or with peaceful tankmates. Can be housed without a hosting anemone.

If maintained with a hosting anemone, aquarium size should be >50 gallons.

Females are larger than males.

If the female is removed, the male will change sex and one of the juveniles will become the new functioning male.
