Arrow crabs, Stenorhynchus seticornis, are an all time favorite for marine aquariums. These spindly crabs are a lot more rugged than they look, and will do well in most types of aquarium set-ups. They are easy to care for and will actively grab any type of food offered to them during feeding times. We prefer to ship the smaller specimens because the great big ones can be ornery and don’t tend to ship as well. The arrow crabs are NOT reef safe as they like to rip apart mushrooms and other soft corals.
Note: Arrow Crabs have been known to crawl out of small acclimation buckets or rimless tanks/sumps where the water level is close to the rim. Please be aware of this so that you can cover the lid or lower the water level so that the arrow crab cannot escape.
