Origin
Found throughout the Indo-Pacific and Caribbean regions, often inhabiting coral reefs, sandy bottoms, and seagrass beds.

Visual & Functional Appeal
Delicate and often semi-transparent, many commensal shrimp display stripes, spots, or color hints that help them blend into their host. Their movement is gentle and rhythmic, and they often perch or sway alongside their symbiotic partners.

Purpose
Add ecological authenticity and behavioral depth to reef tanks. Some assist with light cleaning duties by feeding on detritus near their host. Others simply act as fascinating observers of host-animal dynamics.

Importance
Ideal for biotope purists or reef aquarists focused on mimicking natural symbioses. Their behavior adds micro-drama and biological storytelling to marine displays.

Included Resources
Requires stable reef-quality water parameters, peaceful tankmates, and compatible host animals. Gentle flow and micro-caves or coral perches aid comfort. They benefit from occasional spot-feeding if hosts don’t provide enough food scraps.

Best Use Cases
Nano reefs, anemone tanks, or detailed Indo-Pacific reef simulations. Pair with urchins, anemones, or sea cucumbers depending on species.

Conservation Context
Many species are wild-caught, though their demand is low relative to fish and coral. Avoid overcollection by selecting captive-bred shrimp when available or purchasing from trusted, low-impact suppliers.

Ideal Aquatic Species
• Bubble tip or rock anemones
• Pencil urchins or long-spined urchins
• Sand-sifting sea cucumbers
• Small peaceful reef fish (gobies, firefish)
• Other shrimp (if enough space and hosts)
