He just shed his skin 2day so may be a bit larger now. Here for sale is 1 beautiful crayfish..I called him Harry. He's still young and will grow more..at the mo he's about 6 inches. He's very shy and will need 2 b cared for by some1 with a bit of experience in looking after these stunning creatures. Will be fine with guppies as they are not bottom dwelling and he is. Harry is the best escape artist I have known.. he needs a large ish tank and also with no 1 who can hurt him or him hurt them...make sure yr lid is tight and no holes he can escape..and he deff will. He is eating well and looks 2 b very healthy.
