Symptoms: Cannot swim. By that, I mean, she can't use her fins at all? She uses her HEAD to anchor herself and drags her body along on the gravel....if startled, she tries desperately to swim, by agitating her entire body, and ends up spiraling all over the tank, usually ending up on her face, or her side. She is also BENT when she tries to move. Like your finger, bending the top bit, so you''ve got almost an L shape. That's her.
We've isolated her. She seems to still be eating. The entire tank is fine, besides her, but we DID just have an ich outbreak. Small, but notable in that she started exhibiting the symptoms right after.
She also has to bumps on her top. Not bumps like pimples, growths, or anything like that. It looks like her spine is kinked.
My husband says that when she DOES try to swim, she's only using one side of her fins (I can't look that closely, it is a truly horrid thing to watch

All our other loaches are happy and healthy. Ditto the other fish.
It's been three nights now of this. She's breathing VERY harshly, or not at all. And she's completely rigid....I keep thinking she's gone but then I scare her when I go to check, and I see her wiggling around helplessly all over again, bashing into everything.
I've given her broccoli, as directed on the forums (blanched, and cooled and cut into bits, which I lay next to her head, because she cannot forage at all....) in case it's constipation w/swim bladder. No poo yet. She *was* very healthy! Very fat and lively, and a flirt to boot.
When is it time to call it quits. Three nights? Ten? How long do I wait to say "this is torturous"?
I really, REALLY need some thoughts on this. She's our oldest fish, I Hate seeing her suffer, but I don't want to cut short a life that might just be a little out of sync right now.
Please what would you do...how long do you wait?
