Marine invertebrates cover all the fascinating non-fish life that brings a reef to life – from shrimps, crabs and snails to starfish, urchins and cucumbers. Many are essential members of the clean-up crew, helping to control algae, turn over the sand and clear up leftover food, while others are striking display animals in their own right. Most are reef-safe, but some have very specific needs or may not mix with certain fish or corals, so it’s always worth checking compatibility before you buy. Choose the right mix and your inverts will boost both the health and the visual interest of your marine aquarium.
