My 12.5" polli hassuddenly become very ill. For a couple of weeks it has not eaten and it has laid on the bottom with its backend raised off the bottom as if it is curved. Last night it has suddenly lost all equilibrium and balance and is positioning itself in bizarre movements. It is not really swimming at all. One minute it is vertical, the next it is lying upside down and if it does try and move it tends to just spin round midwater but not actually move.
I am close to euthanising it but then it seems to pick up very slightly but then go back to this pattern again.
The parameters are fine is the tank and so are the rest of the fish. It is the biggest fish in the tank by far. It's normally was eating frozen prawns. It has no marks on it at all and has always been really fat because it eats so well

Is the best you think to euthanise it? Any help is much appreciated thanks
 
None that I can see. She's still hanging on but doesn't look we'll-mostly staying vertical, breathing slowly and when tries to swim goes straight up vertical but spins.
Do you think it's mostly due to the prawn diet? I've read it can lead to problems

^ what EC said if that's literally all you fed it, that's why I stick to pellet

Learnt my lesson-will it recover you think? I've binned the prawn ans won't be using it again
It's looking slightly better in that it can get on the bottom now and keep its position better-doesn't spin as bad when it rises for air too
 
Also sounds like possible vitamin B deficiency from the diet high in thiaminase.

^ that too I just didn't want to make the OP feel worse but it might, get it on some tilapia and earthworms and it'll be better. As far as how to get it out of the state its currently in, I would start a thread under the Freshwater Diseases and Health subforum

Thanks for the help again. Having researched I'm certain it's lack of B1. Just depends if I can get it to feed again now I guess
 
Sorry this happened rob. I learned the hard way too. Back in 2006 I used to feed a diet high in shrimp and I lost a bichir because of it.
