I'm sorry for your fish. Is it still moving or is it gone?
I had this, I tried everything, I noted it in the "what did you do with your aquarium today thread" somewhere around post 5500
It went on for a few months, there is nothing you can do, believe me I tried everything I could possibly think of until such time that I considered it cruelty.
Sorry.
(Somedays fine, some days mistakenly considered dead)
It's gone .'i think it literally had like a stroke or something. I seriously watched it just jerk to the top of the tank and kinda just spaz out...
.
Just curious, did it act like a dolphin, kind of half jumping backward? This happened to a pleco of mine and I'm wondering if that is what you mean by jerking at the top. My guy didn't make it either. I was unable to figure out what happened. Sorry for your loss.
