Thanks Wilder, that was what I was planning to do. If this round of Tetracycline doesn't do anything, then I will just put her back in the main tank. She doesn't seem to be suffering at all. I know some people would say to euthanize her but I just can't seem to justify that when her only problem is that she occasionally swims funny. Oh well, she only has 3 days left of this treatment, so we will see what happens.
Thanks again.
