Description
Tiger Angelfish – Apolemichthys kingii
Apolemichthys kingii, known as the Tiger Angelfish, is an exceptionally rare and captivating deepwater species found only in the Indian Ocean off Western Australia and nearby regions. Its bold golden body, overlaid with intricate black vertical striping, gives it a tiger-like appearance that commands attention in any display. Due to its restricted range and depth of occurrence, this angelfish is seldom seen in the aquarium trade, making it one of the most coveted species among marine collectors.

Collector’s Note: Apolemichthys kingii ranks among the rarest and most exclusive marine angelfish in the world, with limited collection restricted to Western Australian deep reefs. Each specimen’s journey from the twilight zone to the aquarium trade involves meticulous decompression and handling, making this species a true centerpiece for elite “Collector’s Corner” displays.
