Sponge Crab

Dromia crabs are often found in shallow tropical and subtropical waters, living among coral reefs and rocky substrates. They have a close association with various species of sponges, which they use for camouflage and protection. Dromia crabs are believed to be omnivorous, feeding on a variety of organic matter including small organisms, detritus, and algae present within the sponge environment. It's essential to avoid using copper-based treatments in a tank with invertebrates, as it can harm them. Always follow the recommended guidelines for medication use in marine aquariums.

Dromia Crabs are sometimes known as Sponge Crabs do to their habit of decorating their carapaces with sponges which provides camouflage and protection. They are sometimes seen in the aquarium trade. The coloration of Dromia crabs can vary, but they are often somewhat cryptic and may display colors that help them blend in with their sponge camouflage. They can grow up to 4".
