Halloween Hermit Crabs for sale on Halloween?? It might just be crazy enough to work!!

These crabs are great at eating detritus, green hair algae, and cyanobacteria. The large shells they live in tend to stir the sand as they walk around and aerate the substrate. With their orange body and different shape, they can provide more variation to your existing clean-up crew! Like everything at Halloween though, they can have a dark side. Those large shells can disrupt loose corals and rocks. If there’s not enough food, or if there’s a bigger shell that they’d like as a new home, they can take it by force. Keeping extra empty conch shells laying around the bottom of the tank will help this.
