A friend of mine told me about a pet name game - when she first told me I thought she was nuts (LOL) but my husband and I did it and that's how we named both our fish.
Start with the letter A and think of any name that comes to mind... continue on with the alaphabet all the way to Z - its amazing what you can come up with. My husband and I were laughing our heads off because he's a goof and came up with all kinds of goofy names.
I have two betta's - one is named Giovanni (we call him "G" for short...LOL) and the other one is named Iggy. LOL
Try it!
A = Ariel
B = Betsy
C = Carmella
D = Daisy
E = Eva
LOL Those are the 1st things that came to my mind this time around and every time you do it different names come up - I bet you'll come up with a ton of names.

Make sure you go through the entire alphabet though.
