White Tail Tang – Acanthurus thompsoni

Overview:
The White Tail Tang is a striking and active marine herbivore, featuring a dark gray to bluish body with a prominent bright white tail and subtle blue highlights along the fins. Its peaceful temperament and elegant swimming make it a standout in large reef aquariums.

Origin:
Native to the Indo-Pacific, typically found on coral reefs and lagoons from East Africa to the central Pacific.

Feeding:
Primarily herbivorous – thrives on marine algae, seaweed, and spirulina-based foods, supplemented occasionally with meaty foods like mysis shrimp to support balanced nutrition and vibrant coloration.

Tank Mates:
Best kept with peaceful to moderately semi-aggressive fish. Can coexist with other tangs if the aquarium is spacious enough to minimize territorial disputes.

Aggression:
Mildly territorial – may defend grazing or swimming areas, but generally peaceful in mature aquariums with adequate space.

Experience Level:
Intermediate aquarists – requires a mature, stable aquarium with ample swimming space and consistent feeding.
