I always love hearing the stories of people naming their fish, so ramble on.
Drew is a natural alpha and likes to be paid attention to. I named her after a charcher in Rick Riordan's The Lost Hero (a daughter of Aphrodite)
Luna is a night-dweller and is quiet but really weird. She hides in weird nooks and even disappears sometimes. I named her after Luna Lovegood.
I'm planning on getting some new girls tomorrow and might use Aela (The Huntress from Skyrim), Clove (from Hunger Games), and Azura (Skyrim) as names if the girls fit the names.
