This intersting looking crab appears more spiderlike than anything else. They are generally reef safe, but larger ones might tear at softer corals or harass smaller fish. |

The Arrow Crab (Stenorhynchus seticornis) is sometimes called a Spider Crab. It belongs to the family named Majidae. Typically reaching a max size of about 8.0 inches in length, the Arrow Crab is semi-aggressive in nature and hardy in stamina. It's more active during the daytime and less at night, and will hang out or do best in the rock structures. According to FishDB current data, captive breeding success is low and there are no external signs of sexual differences. Stenorhynchus seticornis in general should have standard (3 watts/gallon) light to thrive. Tank parameters should be maintained with ph level between 8.1 - 8.3, temperature between 77 - 79 degrees fahrenheit, and a salinity between 1.020 - 1.023. Some of the environmental concerns that you should strive to replicate in your home aquaria to promote succesful acclimation include rockwork structure.
