Some interesting names for girl lobsters:
Buy a book that teaches you about lobsters (or crayfish), and set up its tank after reading the book and the tips I've provided in the Care and Feeding section, before you take it home.
Basically, you will need a ten gallon aquarium with a filter and a tight-fitting top, among other things. The tight-fitting top is important because lobsters are the Harry Houdinis of the seas - they are excellent escape artists. If not with the help of their pincers, they can escape by jumping out of the aquarium like fish sometimes do!
The one you choose should be alert, although there's no real way of telling just how alert he is because they often lie motionless in their tanks.
Make sure you choose just one li'l critter for your tank, because they are very territorial, and their parents never teach them to share anything, least of all their homes. If kept together, they will often fight to the death, and a lobster without a claw is a sorry sight.
You will also learn how to 'cycle' your aquarium from the book on caring for lobsters, and this is essential measure you must take if you want to keep your lobster clapping its claws!
The trick is never to over-feed them, as uneaten food could contaminate the tank quickly. Fish flakes are great for baby lobbies, while shrimp pellets are perfect for adults.
Two large crushed flakes a day are plenty for babies, one in the morning and another in the evening. For adults, a large pellet for breakfast and then another for dinner should do it. You can also try feeding them water lettuce, water hyacinth, water cress and romaine lettuce. Don't try other kinds of foods, such as meat or such other types of food meant for humans.
