Before you choose from this collection
Every marine invertebrate on this page is a live animal held in our own system before dispatch — not a stock photo. We stock cleaner and hermit crabs, turbo and nassarius snails, starfish, sea urchins, anemones and more, with new imports landing regularly.
Marine inverts ship in oxygen-charged bags inside an insulated box, dispatched Wednesday for Thursday delivery with a licensed live-animal courier so your animals never sit over a weekend. Every order carries our live arrival guarantee: film a short, continuous unboxing video and tell us the same day, and we refund or replace.
Marine invertebrates are the reef's clean-up crew and living jewellery — snails and crabs that graze algae and sift sand, plus anemones and echinoderms for the display. They are sensitive to water quality and copper, so a stable, mature reef system is essential. Research each animal before ordering.

Frequently asked questions
A clean-up crew of snails, hermit crabs and other grazers keeps a reef tank tidy — eating algae off rock and glass, sifting detritus from the sand and consuming leftover food. They are a working part of the system's biology, not just decoration, and reduce the algae and waste that would otherwise build up.
