They are too cute when little. I too just got a copper and a GFP purple, along with a leucistic het for the purple. Love to watch them slurp up blackworms like spaghetti.
My copper is Artemis and my GPF purple is Isis. I do not have a name for the leucistic yet.
Hmm let's see for some mobster names.....
Muscles, Paulie, Tony, Vincenzo (Vinny), Frankie, Lou....
Then all you need to is add an object or adjective to it to make it sound "official"
Frankie Knuckles, Big Tony, Mack the Knife, Lil Dom, Tommy the Butcher, etc.
