I feel your pain! I'm always trying to justify another tank, a new fish, when I see one that speaks to me. Not too long ago I set myself a limit of 4 tanks... and well, I have 7 now. See how well that worked for me?
My lovely bettas are: Dagger, Egg, Salsa, Marble, Augustus, Miles
Puddles, Oz, Nate, Monkey, Picasso, Feng, and Maui
