i think Theo's blindness is both the way he was born, and the care he got at the pet store. he was there over a week, they said, and only three people there care for the fish the right way. x: so, who knows how long he sat in that half gallon 'tank' in nasty water until the good people changed it. Dx
yeah, those thousand dollar ones bug me. as they said, the breeder is known to end up with odd mutations, and try to sell it as a new thing. i once saw a betta who had NO tail, being sold as a mini betta. it's like, her body was so short, the tail and anal fin fused. :< poor girl. i mean, he has some BEAUTIFUL bettas! but... he sells mutations as cool things, when they're not.
