At Reef eScape, we offer a variety of reef aquarium crabs that are essential members of your  cleanup crew. From Emerald Crabs that control nuisance algae to Hermit Crabs and Pitho Crabs that help manage detritus and uneaten food, each species plays a vital role in maintaining a balanced, healthy reef ecosystem. Crabs are natural scavengers, reaching into rock crevices and substrate areas that other cleanup crew members may miss, keeping your tank clean while reducing nutrient buildup. In addition to their functional benefits, many crabs add unique movement and visual interest to a reef display. Whether looking for hardworking invertebrates to maintain water quality or striking species to enhance the aesthetics of your aquarium, our reefing experts at Reef eScape are ready to guide in selecting the perfect crabs.
