Halloween Crabs

Halloween hermit crabs are nocturnal creatures. They will typically rest during the day, and come out at night.  

In general, they are pretty active and always looking for food. However, they do sometimes spend a lot of time inside the shell without movement.

Unfortunately, Halloween hermit crabs are not completely harmless, especially when we are talking about shells. However, they can coexist peacefully with other tankmates if they have everything they need. 

Feeding them is easy because Halloween hermit crabs are omnivores. They are great scavengers and clean up crew. They will eat absolutely anything they can find in your tank, including detritus, leftovers, dead organisms, green hair algae, and cyanobacteria.

The benefit to their natural diet is that their taste for algae means that Halloween hermit crabs will naturally rid your aquarium of excess algae. However, do not fall into a trap by thinking that once they are scavengers. They will take care of themselves. Of course, they will… by becoming more aggressive.

Feed your Halloween hermit crabs once or twice a week. For example, you can feed them – raw table shrimp, frozen mysis shrimp, silver sides, scallop, clam, mussel, and algae tablets. Yes, do not forget about algae. If there is no algae in your tank, give them algae tablets.
