The Peacock-tail Anemone Shrimp (Periclimenes brevicarpalis) is one of the most photogenic macro subjects on an Indo-Pacific reef. With its glass-clear body, bold white saddle patches, and blue-tipped claws and legs, this tiny commensal shrimp turns an ordinary anemone into a stage.
A Siladen Encounter: Filmed off the coast of Siladen Island in North Sulawesi, this shrimp was tucked into the tentacles of its host anemone — living the symbiotic life it’s built for. At just a few centimeters long, it’s the kind of subject you’d swim right past without a sharp-eyed guide or a patient macro eye.
Hovering a few inches off the anemone to keep the camera steady, I watched this shrimp go about its business completely unbothered. It’s a reminder that some of the best subjects in Indonesia are the smallest — and that the reefs around Siladen deliver world-class macro within minutes of the shore.
A Symbiotic Life: Peacock-tail Anemone Shrimp live in close partnership with several species of sea anemone, including carpet anemones (Stichodactyla spp.) and bubble-tip anemones (Entacmaea quadricolor). The shrimp gains shelter and protection from predators — safe among the anemone’s stinging tentacles — while offering cleaning services in return, removing parasites and debris. Like clownfish, they acclimate gradually to the anemone’s sting and develop an immunity that lets them move freely through the tentacles.
Sexual Dimorphism: Females are dramatically larger than males and are the individuals most often photographed. Mature females frequently carry a visible clutch of green eggs tucked beneath the abdomen. Males are tiny by comparison and often go unnoticed on the same anemone.
A Macro Favorite: The combination of transparent body, high-contrast white patches, and metallic blue accents makes Periclimenes brevicarpalis one of the most sought-after subjects in Lembeh, Bunaken, and the wider Coral Triangle. They hold still long enough to compose carefully — a rare gift in underwater macro work.
Also Seen Across the Coral Triangle: Siladen isn’t the only place I’ve filmed these shrimp. They turn up regularly on anemones throughout North Sulawesi and the wider region — including on dives logged in Lembeh Strait and around Bunaken Marine Park.
The Shot (Gear Talk): With macro subjects this small, patience matters as much as gear. The footage was captured on a Panasonic GH5 with an Olympus 60mm macro — a lens well suited for isolating tiny subjects while preserving detail and working distance. The rig rewards slow movement, careful positioning, and restraint around delicate hosts like the anemone. The hardest part was holding steady long enough for the shrimp to return to its natural behavior, with buoyancy control and the careful placement of two soft video lights playing a major role in the final result.
