I did as you said Nossie...quarentined her and found out that she eats like a horse. So I don't have to worry too much about her competing.
I don't think her mouth will ever be shaped like a "normal" goldfish's mouth...one side is pretty sunken in on the inside, but I've discovered I'm already getting attatched to her! Will post photos when I get some for ya.
Oh and ONE OF CRYSTAL'S SCALES IS GROWING BACK!!! It is still a little transparent, but I can see it shining in good lighting. Think that salt helped...thanks for the idea Nossie! 2 down, 1 to go lol. Gotta post photos of that too.
