Hello every one;
About 3 month ago i came down in the morning and found that both of my filters stopped operating due to prefilters being blocked ,all the fish were distressed near the top of the water ,my 5 years old blue turq was head down in the plant pot breathing the foul water of the plant pot , i deblocked the prefilters ,50% w/changed , came back fro work ,all the fish were o.k apart from the blue turq.

He has been head standing and eventually kind of drift in water with no particular direction and some tome lies on the floor ,but he is still eating and has no other sign of any infection i.e he has clear eyes ,no pop eye or fluid buildup or any lump in the body ,

I have treated him with epsom salt and later with API furan -2 but not very much happened .
I know this is a difficult infection to treat but i can't get myself to put him down , i have metro ,minocycline ,nitrofurantoin available , has any body had experience with this problem ,please let me know .
thanks
Sayid
