Hi, I've been looking for a blue lobster for myself and I found a really good site....www.bluecrayfish.com...it has some info on how to care for them feed etc. hope this helps ya.
Its really quite easy to sex them once u know how to do it. Look onder the tail there u will see some feather like fins in rows of two. Depending on the number of rows and the size of the fins u will be able to tell if the lobster is male or female. (unfortunatly i don't remember which one is which) srry
