Remember my crooked molly? She seems to be getting worse. The more I look at her the more she looks like she was wrapped around the filter intake and miraculously got free. She doesn't seem especially unhappy except for the fact that it is getting harder and harder for her to swim. She's in a tank with some very placid platys now, so she's not in danger, but it just looks like it's getting tough on her. I don't think she's going to get better. Should I put her in the freezer? I don't really even know a good way to euthanize a small tropical fish. I'm not sure the freezer is humane.
