Saltwater Inverts

Saltwater Invertebrates for Sale

Saltwater invertebrates are a diverse and essential part of the reef aquarium hobby, serving functional roles as cleanup crew members while adding color and biological interest to the tank. On Light Fish you'll find saltwater inverts listed by reef hobbyists and small-scale breeders, including hermit crabs, snails (astrea, cerith, nassarius, turbo), cleaner shrimp, peppermint shrimp, sea urchins, and starfish. A well-selected cleanup crew is one of the most important investments in a healthy reef system.

All saltwater invertebrate orders on Light Fish are backed by a platform-wide Live Arrival Guarantee. Inverts are packed in heat-sealed breather bags with temperature-appropriate packs, shipped in insulated boxes via priority or overnight carrier, and weather-monitored to ensure safe transit. Invertebrates are extremely sensitive to copper — never use copper-based medications in a reef or invert tank. Acclimate new arrivals slowly using the drip method to prevent osmotic shock.
