Periclimenes brevicarpalis (S) – Anemone Shrimp 4 cm

Overview

Periclimenes brevicarpalis, often sold as the anemone shrimp, is a fascinating marine invertebrate prized for its delicate appearance and symbiotic lifestyle. This small Indo-Pacific shrimp is best known for living among sea anemones, where it gains protection from predators while helping to keep the host clean. With its translucent body, contrasting markings and graceful movement, it makes a captivating addition to a mature reef aquarium.

At around 4 cm in size, this species is best suited to experienced marine keepers who can provide stable water conditions and suitable host anemones or a carefully planned reef environment. It is generally peaceful and reef-compatible, though it should be kept with appropriate tankmates and plenty of hiding places. As with all live marine livestock, we recommend a fully cycled aquarium and careful acclimation on arrival. Your order is covered by our live arrival guarantee, and we offer fast UK delivery to help your shrimp arrive in excellent condition.

Periclimenes brevicarpalis is a wonderful choice for aquarists who enjoy observing natural behaviour. Rather than being a purely decorative shrimp, it is an active, interactive species that spends much of its time perched within the tentacles of its host. In the right setup, it can become one of the most interesting animals in the tank.

Care at a Glance

Origin & Natural Habitat

Periclimenes brevicarpalis is native to the tropical Indo-Pacific, where it inhabits coral reef systems, lagoons and sheltered coastal areas. In the wild, it is most commonly associated with sea anemones, particularly large host species that provide both shelter and a feeding platform. This relationship is a classic example of symbiosis: the shrimp receives protection from predators, while the anemone may benefit from cleaning and the removal of small food particles.

The species is adapted to warm, stable marine conditions with excellent water quality and moderate water movement. It is not a hardy brackish or temperate species; instead, it requires a true marine reef environment with consistent salinity and carefully maintained parameters. Because of its specialised lifestyle, it is best kept by aquarists who already have experience with reef systems or who are prepared to research its needs thoroughly before purchase.

Tank Setup & Water Parameters

A mature reef aquarium is the ideal home for Periclimenes brevicarpalis. A minimum of 70 litres is recommended, although larger systems are always more stable and provide more room for compatible tankmates. The tank should be fully cycled, with low nitrate, zero ammonia and zero nitrite. Stable salinity is essential, and sudden changes should be avoided.

If you plan to keep this shrimp with a host anemone, choose a species that is appropriate for your tank size and lighting, and ensure the anemone is settled before introducing the shrimp. Suitable rockwork and crevices will help the shrimp feel secure, while gentle to moderate flow will mimic its natural reef habitat. Fine sand is optional, but live rock and a mature biological filter are highly beneficial.

Recommended water parameters:

• Temperature: 24–28°C
• pH: 8.1–8.4
• Specific gravity: 1.023–1.026
• Ammonia/Nitrite: 0
• Nitrate: ideally under 10–20 ppm

As with all marine invertebrates, copper-based medications are highly dangerous and should never be used in a tank housing this shrimp. Provide stable conditions, regular maintenance and careful acclimation using a drip method where possible. Good oxygenation and a secure lid are also sensible, especially in reef systems with active circulation.

Feeding Guide

Periclimenes brevicarpalis is an omnivorous scavenger with a preference for small meaty foods. In the aquarium it will often pick at leftover food, detritus and tiny organic particles, but it should not be expected to live on leftovers alone. Offer a varied diet to support health and colouration.

Suitable foods include finely chopped marine mysis, enriched brine shrimp, copepods, krill fragments, quality frozen marine blends and sinking invertebrate pellets or granules. Feed small amounts several times per week, or more often in a lightly stocked tank. If the shrimp is living with a host anemone, it may spend much of its time within the tentacles and feed opportunistically when food is introduced nearby.

Because this species is small, overfeeding can quickly pollute the water. Offer only what can be consumed promptly, and remove uneaten food after feeding. A varied diet and excellent water quality are the keys to long-term success.

Tank Mates / Compatibility

This shrimp is generally peaceful and best kept with calm, reef-safe tankmates that will not harass or prey upon it. Suitable companions include small gobies, blennies, clownfish in appropriate reef setups, peaceful wrasses of suitable size, chromis, and other non-aggressive reef fish. It can also be housed with many corals and invertebrates, provided the system is stable and not overcrowded.

However, avoid large predatory fish, aggressive wrasses, hawkfish, triggers, puffers, lionfish and any species likely to view the shrimp as food. Very boisterous tankmates may also stress it and prevent natural behaviour. If keeping multiple shrimps or other ornamental crustaceans, ensure the aquarium is large enough and that there is enough shelter to reduce competition.

In many cases, the best display for this species is a dedicated reef aquarium with a suitable anemone host and carefully chosen peaceful fish. This allows the shrimp to exhibit its natural behaviour and remain secure.
