overview
  
The Emerald Crab (Mithrax sculptus) is sometimes called an Emerald Mithrax Crab. It belongs to the family named Majidae. Typically reaching a max size of about 3.0 inches in length, the Emerald 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 unreported and there are no external signs of sexual differences. Mithrax sculptus 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 and plenty of hiding spaces.
