I have had a blue lobster in a 55 gal tank in my home for 3 years. He has grown from 1.5 inches long to almost 8 inches! Do not put anything in with a lobster that you want to see the next day....They are territorial, night hunters and will wait patiently for their prey. I have a large clown loach and a large chinese algae eater in with my blue and they seem to get along (pardon the pun) swimmingly. Give the lobster palces to hide and interesting places to climb. You will find that he rules the tank and any tank mates will go the the opposite end of the ocean to stay out of his way. Lobsters (they are really crayfish, but whatever) prefer a slightly cooler tank 76 to 78 degrees, so choose his mates accordingly.
