Mine are dumber than a box of rocks, but they're sure cute. X3 Which is all that counts. I feed them and take care of them so they don't need to be very witty.
Goldfish C is my favorite out of them all. I have a pearlscale in the pond too now, but no photos. ;_; Have to wait until next year.
I'd love a Tosakin, but I'm told they're rather delicate on top of being really expensive.
