When I woke up this morning my fish was twitching! Jerking!
--He can't stay in one place without jerking his head from side to side, and he can't swim smoothly.
--Whatever has been eating at his tail made a lot of headway in the night. I thought it was fin rot, but it doesn't seem to have a dark edge anymore, yet more and more of the tail is gone. It doesn't look bitten off--it's all the delicate part that's gone, but the rays are still there.
--In the last four days, I've done two 100% water changes, added the filter, and added aquarium salt, but he's only gotten (drastically!!!) worse!
