notes
   A fascinating fish. It's bizarre shape makes it look more alien than of this world. With proper care, this can be a long lived addition to your tank. Take care not to house with very aggressive tankmates for two reasons. One, it's not an aggressive feeder, so if it must compete for its food it may starve. Two, if it becomes too stressed it can exude a lethal toxin, killing all tankmates.   
overview
  
The Cube Boxfish (Ostracion cubicus) is sometimes called a Yellow Boxfish, a Polka Dot Boxfish, or a Cubicus Boxfish. It belongs to the family named Ostraciidae. Typically reaching a max size of about 17.8 inches in length, the Cube Boxfish is semi-aggressive in nature and risky in stamina. It's more active during the daytime and less at night, and will hang out or do best in the middle tank area. According to FishDB current data, captive breeding success is unlikely and there are no external signs of sexual differences. Ostracion cubicus should not be housed in a tank less than 140 gallons in size. 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 extra swimming area, plenty of hiding places, and a stable cave/sheltering ledge.
