Decorator Crab

The Macrocoeloma trispinosum, commonly known as the Decor Crab, is a fascinating crustacean that disguises itself by attaching algae, sponges, or dead coral pieces to its carapace. Native to the reefs of the Western Atlantic and Caribbean, this crab is an excellent detritivore, helping to clean aquariums by feeding on organic waste and algae. However, due to its opportunistic behavior, it should be monitored in reef tanks, as it may occasionally prey on small invertebrates or soft corals.
