Temperment: Keep this one in a tank with larger fish such as cichlids. They cannot be trusted with slower, smaller fish. They live on the bottom of the tank and like to hide alot of the time.

Comments: They are territorial with their own kind, so if you plan to have more than one, make sure you have a tank larger than 25 gallons. Often called Blue Lobsters, but are not true lobsters as lobsters are saltwater creatures. They like to dig and bury, so ensure that they have some sand and rocks to play in.
