Ya, today when we got home from church, our black mollie was kind of floatie, like she's dying. The odd thing is is that she's a sailfin but now the black on her tail is split like [ except much more extreme. She was perfectly normal yesterday even late last night.and this morning So my question is, what on earth can she have, and how do I fix it. She is heavily preg if that helps anything, she doesn't seem as though she's giving birth because eshe isn't quite big enough.
